Abstract

The quasi-elastic scattering and the one-nucleon transfer channels of ³²S + ⁶⁴Ni have been studied using the LNL Recoil Mass Spectrometer. The excitation function at θ_c.m. = 170° from E_lab = 68.3 to 92.4 MeV and an angular distribution at E_lab = 81.3 MeV from θ_c.m. = 120° to 170° have been measured. The results have been analyzed in the framework of the complex WKB approximation and in the semiclassical approximation based on Coulomb trajectories.

Nuclear Data Sheets for A=64
2021, Nuclear Data Sheets
The evaluated experimental data are presented and evaluated for 13 known nuclides of mass 64 (Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Se). For each nuclide, the best values combining all available data are recommended for spectroscopic properties. No excited states have been identified in ⁶⁴Ti, ⁶⁴As, and ⁶⁴Se. Only one excited state in ⁶⁴V as an isomer, and three in ⁶⁴Cr have been identified. Data for excited states in ⁶⁴Mn, ⁶⁴Fe, and ⁶⁴Co remain limited. ⁶⁴Ni, ⁶⁴Cu, and ⁶⁴Zn are the most studied nuclides through various reactions and decays, followed by ⁶⁴Ga and ⁶⁴Ge. In the opinion of the evaluators, there are several incomplete or discrepant aspects of the high-spin portion of the level scheme for ⁶⁴Zn above ≈5 MeV excitation which need to be resolved in further experiments using large γ-detector arrays. The decay schemes of ⁶⁴Ti β⁻, ⁶⁴As ε and ⁶⁴Se ε are unknown, while very little information is available for ⁶⁴V β⁻ and ⁶⁴Cr β⁻. The decay schemes of ⁶⁴Mn β⁻, ⁶⁴Fe β⁻, ⁶⁴Co β⁻ and ⁶⁴Ge ε are somewhat better known, but still considered incomplete by evaluators. The decay scheme of ⁶⁴Ga ε decay is known in detail, however there is the possibility of additional levels populated above 4713 keV, as the Q(ε) value is 7171 keV. The β⁻, β⁺ and ε decay modes of ⁶⁴Cu are well known, as this radionuclide is of great importance in applications, for example, as a dosimeter for neutron flux determination in nuclear reactors, and as a radiopharmaceutical for positron emission tomography (PET). This work supersedes earlier full evaluations of A=64 by 2007Si04, 1996Si12, 1991Si03, 1979Ha35 and 1974Au04.
Reaction mechanism and nuclear structure explored in binary reactions: status and perspectives
2007, Nuclear Physics A
Recent advances have been achieved in the field of multinucleon transfer reactions among heavy ions, both experimentally and theoretically. Detailed nuclear mass, charge and Q-value distributions allow to identify the relevant degrees of freedom acting in the transfer process. The advent of the large solid angle magnetic spectrometer PRISMA coupled to the large γ-array CLARA was a major experimental breakthrough, as reaction mechanism and nuclear structure studies of neutron rich nuclei can be performed via γ-particle coincidences. Examples of recent studies are presented.

The evaluated spectroscopic data are presented for known nuclides of mass 64 (V,Cr,Mn,Fe,Co,Ni,Cu,Zn,Ga,Ge,As,Se). Excited-state data are nonexistent for ⁶⁴V, ⁶⁴Cr, ⁶⁴As and ⁶⁴Se. Except for half-lives, no other radioactive decay data are available for the decay of ⁶⁴V, ⁶⁴As and ⁶⁴Se; and those for the decays of ⁶⁴Cr, ⁶⁴Mn, ⁶⁴Fe, ⁶⁴Co and ⁶⁴Ge are not considered as definitive. There are several high-spin studies for ⁶⁴Zn nuclide, but many inconsistencies are noted in this evaluation and complete details of data in these studies are generally lacking in the published literature. This work supersedes earlier full evaluations of A = 64 by 1996Si12, 1979Ha35, 1974Au04 and 1967Ve09; and a mid-strem evaluation by 1991Si03 published in an 'update' mode.

General Comments:The statistical analysis of γ-ray data and deduced level schemes is carried out through computer codes available at Isotopes Project, Berkeley and Nuclear Data Center, Brookhaven. The methodology and procedures for some of these codes are described by 86BrZQ and 86Br21. A general 3% uncertainty is assumed in quoted theoretical internal conversion coefficients taken mainly from 68Ha53.
The values of μ and Q are from compilation by 89Ra17, when available.
Experimental investigation on the connection between nucleon transfer channels and near-barrier fusion in 32S+64Ni and 28Si+68Zn systems
1996, Nuclear Physics A
One- and two-neutron transfer reactions were studied at bombarding energies near the barrier in ³²S+⁶⁴Ni and ²⁸Si+⁶⁸Zn systems using scattered ion-γ-ray coincidence. Transfer probabilities were obtained in coincidence with selected γ-rays of the product nuclei. The missing probabilities due to transfer leading to the ground state of the product nuclei were estimated using known spectroscopic strengths from the light ion transfer reaction data. The form factors for the neutron transfer channels were obtained from these measurements using a semiclassical theory. The known inelastic couplings, together with the experimentally determined transfer form factors were utilized in a simplified coupled channel calculation to obtain fusion cross sections and the average angular momenta. A comparison of these values with the existing data shows that inclusion of the transfer channels with known coupling strengths is essential to achieve a good agreement with the data.
