Available in PDF, EPUB and Kindle. Book excerpt: Transfer reactions have been used for many years to understand the shell structure of nuclei. Recent studies with rare-isotope beams extend this work and make it possible to probe the evolution of shell structure far beyond the valley of stability, requiring measurements in inverse kinematics. We present a novel technical approach to measurements in inverse kinematics, and apply this method to different transfer reactions, each of which probes different properties of light, neutron-rich nuclei.

Book excerpt: Radioactive beam experiments have made it possible to study the structure of nuclei at the neutron drip line. Pair correlations play a crucial role in such nuclei and characteristic features include an extended neutron halo density and a large dipole strength near threshold. The most detailed studies have been performed for 11Li. I will present a 3-body model that explains the main features of the data obtained for this nucleus.

This book was released on 2021-09-23 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: The monograph describes the properties of the lightest nuclei with large excess of neutrons. The results of theoretical and experimental studies of neutron-rich isotopes with 1 ≤ Z ≤ 20 are presented while also changes in the structure of nuclei when going away from the line of β-stability are discussed. Information presented is on the mass, radii of distribution of nuclear matter, energy levels for excited states of these nuclei, the possibility of manifestation of a halo, as well as the deformation of nuclei and the quantum properties of ground states. The position of the boundary of nucleon stability for these nuclei is considered. The effects associated with weakening and even the disappearing influence of standard magic numbers and the appearance of new ones are discussed.The results presented in the book will be useful in other fields of science as well, including astrophysics.

This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of low-lying levels of nuclei near closed shells not only elucidates the evolution of nuclear shell structure far from stability, but also affects estimates of heavy element nucleosynthesis in supernova explosions. Especially, the properties of the low-lying levels in 81Ge[Germanium 81] are important because the sensitivity study of the r-process pointed out that the properties of the nucleus can affect the final bundance pattern. Also, the spins and parities measurements of the states are essential to understand the shape coexistence in odd-mass N = 49 isotones. This work describes the study of the odd-mass N = 49 nucleus, 81Ge in the region of neutron magic number N = 50 using an inverse kinematics (d,p) transfer reaction. The d(80Ge[Germanium 80],p)81Ge neutron transfer reaction was measured by bombarding a 174 μg[microgram]/cm2[centimetersquared] (CD2)n[deuterated polyethylene] target with a 310 MeV beam of radioactive 80Ge at the Holifield Radioactive Ion Beam Facility (HRIBF) at Oak Ridge National Laboratory (ORNL). The new ORNL DAQ ASICs system was commissioned for a first implementation of the development in the experiment. The excitation energies of low-lying levels were measured. From analysis of the observed angular distributions, the spins and the parities were determined, and spectroscopic factors were extracted for the first time. Neutron capture cross sections on 80Ge have been calculated in a direct-semidirect model using extracted spectroscopic factors. Furthermore, two intruder states were confirmed and their properties were compared with other odd-mass N = 49 isotones.

Available in PDF, EPUB and Kindle. Book excerpt: Dramatic progress has been made in all branches of physics since the National Research Council's 1986 decadal survey of the field. The Physics in a New Era series explores these advances and looks ahead to future goals. The series includes assessments of the major subfields and reports on several smaller subfields, and preparation has begun on an overview volume on the unity of physics, its relationships to other fields, and its contributions to national needs. Nuclear Physics is the latest volume of the series. The book describes current activity in understanding nuclear structure and symmetries, the behavior of matter at extreme densities, the role of nuclear physics in astrophysics and cosmology, and the instrumentation and facilities used by the field. It makes recommendations on the resources needed for experimental and theoretical advances in the coming decade.

Book excerpt: Radioactive beam experiments have made it possible to study the structure of light neutron rich nuclei. A characteristic feature is a large dipole strength near threshold. An excellent example is the loosely bound nucleus ''Li for which Coulomb dissociation plays a dominant role in breakup reactions on a high Z target. I will describe a three-body model and apply it to calculate the dipole response of 11Li and the momentum distributions for the three-body breakup reaction: 11Li --> 9Li+n+n, and comparisons will be made to recent three-body coincidence measurements.

Download or read book Structural Evolution in the Neutron rich Nucleus 14B written by Shadi A. Bedoor and published by . This book was released on 2014 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effective single particle energies of shell model orbitals play a decisive role in nuclear structure calculations. The ESPEs set the scale for excited states, and they help determine the strength of configuration mixing for multi particle states. The ESPEs depend on the proton and neutron ratio, and it is interesting to determine how the values of these energies evolve as a function of N/Z, particularly at the limit of nuclear stability. The nucleus 14B, with neutron separation energy of 0.969Mev, is the lightest bound N=9 isotone. The single neutron outside the closed p-shell provides an excellent opportunity to explore the 1s1=2 and 0d5=2 neutron single particle states to, and beyond the limit of stability. In this mass region, for large N/Z, the ordering of the 1s1=2 and 0d5=2 orbitals is inverted as compared to the situation near stability. This inversion is seen, for example, from the ground state spin of 1/2+ for 15C as compared to 5/2+ for 17O, both of which contain a single valence neutron in the sd shell. The same inversion is expected in 14B. The evolution structure of 14B has been investigated using two single nucleon transfer reactions: neutron adding with 13B(d ,p)14B, and proton removal with 15C(d ,3He)14B. From the (d ,p) reaction, the angular momentum and relative spectroscopic factors were deduced for the lowest four negative parity states, namely (21, 11, 31, 41)-. The (d ,3He) results confirm the existence of the broad 2-2 excited state suggested in the literature. Both the (d ,p) and (d ,3He) measurements were conducted using the HELIcal Orbit Spectrometer (HELIOS) at the ATLAS (Argonne Tandem Linac Accelerator System) facility at Argonne National Laboratory. HELIOS is a large solenoid spectrometer specially designed to study transfer and other reactions in inverse kinematics. HELIOS takes advantage of the uniform magnetic field produced by a superconductor solenoid to transport the light charged particles emitted at the target in helical orbits trajectories back to the solenoid axis where they are detected in the array of position sensitive silicon detectors. The heavy beamlike ions 14B (13B) from bound (unbound) states in 14B were detected in the recoil detector at forward angles. The radioactive 13B and 15C beams were produced in the in-flight facility at ATLAS.
