This book was released on 2009 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of nuclei with few nucleons outside the closed shell provides benchmarks for the nuclear shell model especially in this modern era of physics where exotic doubly magic nuclei can be tested. The subject of this thesis is to experimentally investigate the properties of nuclei near 78Ni and to confront them with the predictions of modern large scale shell model calculations. In this regard, an experiment was performed at the National Superconducting Cyclotron Laboratory (NSCL) to measure excited states in 71−73Ni populated via the beta-decay of 71−73Co. Data collected from this experiment lead to partial level schemes for 71Ni and 73Ni and to improvements of existing level schemes for 70Ni and 72Ni. An objective of this experiment was to investigate the changes in excitation energy of the 5/2− state relative to the 9/2 ground state as well as the search for the 1/2− isomeric state in odd-mass nickel isotopes approaching 78Ni. A second experiment was performed also at the NSCL where a two nucleon removal reaction from 73Cu was used to populate the low lying yrast states in 71Ni. Results from this in-beam experiment aided in constructing the level scheme of 71Ni. Systematics in shell model calculations using realistic interactions for odd mass 69−77Ni reveal a steady increase in energy spacing between the 1/2− level and 9/2 ground state - suggesting an increased role of the g9[subscript /]2 correlations, but an almost constant energy separation between the 5/2− and 1/2− excited states. Using data from the two experiments, the position of the 5/2− state in 71Ni and 73Ni and 1/2− state in 71Ni were identified. The decay of 74[superscript,]76Ni into 74[superscript,]76Cu was also investigated. Low lying states revealed new level schemes which are presented with an interpretation of the position of 1+ states populated via allowed GT transitions. A second project in this thesis is on the design and development of a detector system using a dual micro channel plate configuration. The system was built to detect and measure nanosecond isomers in neutron rich 73−76Cu and 76Zn isotopes. The design of the instrument and preliminary beam and alpha source tests done on the system are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Thick-target [gamma][gamma] coincidence techniques are being used to explore the spectroscopy of otherwise hard-to-reach neutron-rich products of deep-inelastic heavy ion reactions. Extensive [gamma][gamma] coincidence measurements were performed at ATLAS using pulsed beams of 8°Se, 136Xe, and 238U on lead-backed {sup 122,124}Sn targets with energies 10-15% above the Coulomb barrier. Gamma-ray coincidence intensities were used to map out yield distributions with A and Z for even-even product nuclei around the target and around the projectile. The main features of the yield patterns are understandable in terms of N/Z equilibration. We had the most success in studying the decays of yrast isomers. Thus far, more than thirty new [mu]s isomers in the Z = 50 region were found and characterized. Making isotopic assignments for previously unknown [gamma]-ray cascades proves to be one of the biggest problems. Our assignments were based (a) on rare overlaps with radioactivity data, (b) on the relative yields with different beams, and (c) on observed cross-coincidences between [gamma] rays from light and heavy reaction partners. However, the primary products of deep inelastic collisions often are sufficiently excited for subsequent neutron evaporation, so [gamma][gamma] cross-coincidence results require careful interpretation.

This book was released on 2021 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discovering unexplored high-spin states in neutron-rich nuclei can open up a new direction to study band structure and the associated shell structure in isospin-asymmetric many-body systems. However, experimental reach has so far been limited to neutron-deficient or stable nuclei which are preferentially produced in fusion reactions used in such studies. By using neutron-rich rare-isotope beams, this limitation can be effectively removed, exposing previously inaccessible nuclei to this proven approach.This dissertation reports an experiment designed to kick off a spectroscopy program to study nuclear structure by means of low-energy nuclear reactions with reaccelerated rare-isotope beams available from the ReA3 facility at National Superconducting Cyclotron Laboratory. A 40Ar stable beam and a 45K rare-isotope beam impinged on a self-supporting lithium target to produce products ranging from argon to titanium via both direct and compound nucleus reactions. These mechanisms provide complementary tools to study the single-particle and collective natures of the states being probed. Using particle and gamma-ray coincidence relations between a silicon charged-particle detector and the Segmented Germanium Array, reaction channels were distinguished, and new properties were revealed, including for the nuclei 46Ca and 47K. For 46Ca, three new higher-lying states around 6 MeV and five new gamma-ray transitions were identified, suggesting three independent band structures formed from different particle-hole configurations. The rotational-like band built on the 0+2 state is established up to the tentatively assigned 6+2 state. New results are compared to large-scale shell model calculations, confirming the validity of the effective interaction describing particle-hole excitations across the Z=20 and N=28 shell gaps in the vicinity of doubly-magic 48Ca. Shape coexistence observed in lighter-mass calcium isotopes is suggested to persist in 46Ca, albeit as part of a transition from neutron to proton cross-shell excitations. For 47K, differential cross sections were extracted for the two-neutron transfer channel related to the present intruder configuration. Comparisons to Coupled Reaction Channels calculations indicate strong single-particle character for the states and a direct one-step process for the reaction itself. This work successfully developed the experimental techniques to use reaccelerated beams for spectroscopy of hitherto unexplored nuclei and demonstrated the ability of this approach to expand the experimental reach of nuclear structure studies.
