Available in PDF, EPUB and Kindle. Book excerpt: An extension of the experimentally known nuclidic mass surface to nuclei far from the region of beta-stability is of fundamental interest in providing a better determination of the input parameters for the various nuclear mass formulae, allowing a more accurate prediction of the ultimate limits of nuclear stability. In addition, a study of the shape of the mass surface in the vicinity of the doubly-closed nuclide 1°°Sn provides initial information on the behavior of the shell closure to be expected when Z = N = 50. Experiments measuring the decay energies of 1°3 1°5In by .beta.-endpoint measurements are described with special attention focused on the development of a plastic scintillator .beta.-telescope coupled to the on-line mass separator RAMA (Recoil Atom Mass Analyzer). An attempt to measure the .beta.-endpoint energy of 1°2In is also briefly described. The experimentally determined decay energies and derived masses for 1°3 1°5In are compared with the predictions of different mass models to identify which models are more successful in this region. Furthermore, the inclusion in these comparisons of the available data on the neutron-rich indium nuclei permits a systematic study of their ground state mass behavior as a function of the neutron number between the shell closures at N = 50 and N = 82. These analyses indicate that the binding energy of 1°3In is 1 MeV larger than predicted by the majority of the mass models. An examination of the Q/sub EC/ surface and the single- and two-neutron separation energies in the vicinity of 1°3 1°5In is also performed to investigate further the deviation and other possible systematic variations in the mass surface in a model-independent way.

Book Beta Decay of Neutron rich Isotopes of Zinc and Gallium

Available in PDF, EPUB and Kindle. Book excerpt: Beta-decays of neutron-rich nuclei near the doubly magic 78Ni [78Ni] were studied at the Holield Radioactive Ion Beam Facility. The half-life and the gamma-gamma coincidence spectra were used to study the nuclear structure. A new 82,83Zn [82Zn, 83Zn] decay-scheme was built, where a 71±7% beta-delayed neutron branching ratio was assigned in 82Zn [82Zn] decay. New gamma-ray lines and energy levels observed in 82,83Ga [82Ga, 83Ga] beta-decay were used to update previously reported decayschemes. The experimental results were compared to shell model calculations, which postulate the existence of Gamow-Teller transitions in these decays. The half-lives of 155±17 and 122±28 ms were determined for 82,83Zn, respectively. In order to enable future studies of very neutron rich isotopes a new detector was developed as a second project. This detector is intended for use in fragmentation type experiments, which require segmentation in order to enable implantation-decay correlations. In addition, the detector requires good timing resolution for neutron time-of-ight experiments. A Position Sensitive Photo-Multiplier Tube (PSPMT) from Hamamatsu coupled with a 16x16 fast pixelated plastic scintillator was used. The PSPMT's anodes form 8x8 segment panel used for position reconstruction. Position localization has been achieved for energies range of 0.5-5 MeV. A single signal dynode (DY12) shows a sufficient time resolution between this signal and the anode's signals, which enable us to used DY12 signal alone as a trigger for timing purposes. The detector's DY12 signals was tested with reference detectors and it provided a sub-nanosecond time resolution through the use of a pulse-shape analysis algorithm, which is sufficient for use in experiments with the requirement for the fast timing. The detector ability to survive after implanting high-energy ions was tested using a laser that simulated energy of 1 GeV. The recovery time of the detector in this situation was 200 nanosecond.

Book Beta decay Beta delayed Neutron Emission and Isomer Studies Around 78Ni

Download or read book Beta decay Beta delayed Neutron Emission and Isomer Studies Around 78Ni written by Mustafa M. Rajabali and published by . 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.
