Abstract

Admixtures of one- and two-phonon states are required to fit (e, e′) form factors for the lowest two 2⁺ states in several even-even vibrational nuclei. These anharmonic wave functions correctly reproduce radiative branching ratios and excited state quadrupole moments.

Nuclear Data Sheets for A=48
2022, Nuclear Data Sheets
Experimental nuclear structure data from various reactions and decays are compiled and evaluated for all known nuclides with mass number A=48 (S, Cl, Ar, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni). For each nuclide, detailed evaluated nuclear structure information is presented for each individual reaction and decay, and the best values combining all available data are recommended for spectroscopic properties, such as level energies, half-lives, γ-ray energies and intensities, decay radiations. No excited states have been identified in ⁴⁸S, ⁴⁸Cl, ⁴⁸Co and ⁴⁸Ni, among which the first three even have no measured ground-state half-lives and decay modes. For ⁴⁸Fe, a level scheme with a sequence of excited states was established for the first time from a recent one-neutron removal measurement by 2021Ya33. Data for excited states in ⁴⁸Ar, ⁴⁸K and ⁴⁸Mn remain limited; no decay scheme has been measured for ⁴⁸Ar and ⁴⁸K yet, while the decay scheme for ⁴⁸Ni is incomplete due to unobserved levels. ⁴⁸Ti is the most studied nuclide through various reactions and decays, followed by ⁴⁸V, ⁴⁰Ca, ⁴⁸Sc, and ⁴⁸Cr, among which no decay event to ⁴⁸Sc has been observed and the decay schemes for ⁴⁸V and ⁴⁸Cr are considered as incomplete. This work supersedes the previous full evaluations of A=48: 2006Bu08, 1993Bu04, 1985Al14, 1978Be01.
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.
Nuclear Data Sheets for A = 70
2016, Nuclear Data Sheets
Spectroscopic data for all nuclei with mass number A = 70 have been evaluated, and the corresponding level schemes from radioactive decay and reaction studies are presented. Since the previous evaluation, the half-life of ⁷⁰Mn has been measured and excited states in ⁷⁰Fe observed for the first time. Excited states in ⁷⁰Ni have been more extensively studied while Coulomb excitation and collinear laser spectroscopy measurements in ⁷⁰Cu have allowed for firm Jπ assignments. Despite new measurements, there remain some discrepancies in half-lives of low lying states in ⁷⁰Zn. New measurements have extended the knowledge of high-spin band structures in ⁷⁰Ge and ⁷⁰As. This evaluation supersedes the prior A = 70 evaluation of 2004Tu09.

2007, Nuclear Data Sheets
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.
