Abstract

The vector analyzing power iT₁₁(θ) and absolute cross section σ(θ) for $^{64} Zn (d, t)^{63} Zn$ and $^{64} Zn (d,^{3} He)^{63} Cu$ have been measured at a deuteron energy of 13.0 MeV. Transitions to three states of ⁶³Zn (E_x = 0.0, 0.19 and 0.25 MeV), and to the g.s. of ⁶³Cu were studied. Measurements of σ(θ) and iT₁₁(θ) were also made for deuteron elastic scattering from ⁶⁴Zn. The analysis of the elastic scattering data provided deuteron optical-model parameters that were used in DWBA calculations. Comparison of the data with DWBA predictions permits the unambiguous determination of J^π for the four transitions studied.

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.

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.

Abstract: The 1991 evaluation of A=63 (1991Ki10) has been revised using available experimental decay and reaction data since the last evaluation. In this evaluation there are some new data and reactions, such as T_1/2 for ⁶³Cr and ⁶³Mn, ¹⁸O(⁴⁸Ca,p2nγ) and ⁶⁴Ni(d,³Heγ) for ⁶³Co, ⁴⁰Ca(²⁸Si,5pγ) and ⁶⁴Zn(d,³Heγ) for ⁶³Cu, ⁴⁰Ca(²⁸Si,4pnγ) and ⁵⁰Cr(¹⁶O,2pnγ) for ⁶³Zn, and ⁴⁰Ca(²⁸Si,αpγ),(³²S,2αpγ) for ⁶³Ga, specifically.

Abstract:The evaluated spectroscopic data are presented for known nuclides of mass 64 (Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge). Excited-state data are nonexistent for⁶⁴Mn and⁶⁴Fe. Radioactive decay data for⁶⁴Mn are not available and those for⁶⁴Fe,⁶⁴Co and⁶⁴Ge are not considered definitive.
The following nuclides have not yet been identified but, amongst other nuclides, have been included in theoretical calculations:⁶⁴Ca (92Ma60,91To03,91Hi10);⁶⁴Cr (95Re20,95Ri05,95Au04);⁶⁴As (95Au04);⁶⁴Se (93Sh11).
The literature available up to June 25, 1996 has been consulted. This work supersedes earlier evaluations of A=64 published in Nuclear Data Sheets (91Si03,79Ha35,74Au04,67Ve09).

Acknowledgments:The evaluator thanks Alfredo Galindo-Uribarri at Chalk River for discussions and communicating results of his recent in-beam experiment on⁶⁴Zn, prior to publication.
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.

The evaluated spectroscopic data are presented for eight known nuclides of mass 64 (Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge). Excited-state data are nonexistent for ⁶⁴Mn and ⁶⁴Fe. Very little information is available for ⁶⁴Ge and γ-ray data are scarce for ⁶⁴Co and ⁶⁴Ni. Some high-spin data are available for ⁶⁴Ga and ⁶⁴Ge, in spite of several in-beam γ-ray experiments on ⁶⁴Zn and ⁶⁴Cu. Further work on ⁶⁴Zn and ⁶⁴Ga seems to be in progress at Daresbury (90LiZS) through heavy-ion reactions. Radioactive decay data for ⁶⁴Mn are not available and those for ⁶⁴Fe, ⁶⁴Co and ⁶⁴Ge are not considered definitive.
