Abstract

The doubly odd nuclei ⁴⁸Sc, ⁵⁰V, ⁵²Mn and ⁵⁴Co have been studied by the charge exchange reaction (³He, t) on ⁴⁸Ca, ⁵⁰Ti, ⁵²Cr and ⁵⁴Fe enriched targets. In addition to the analogue state of the target ground state, we observed a great number of low-lying energy levels, especially those which can be described by the $[(f_{72}) p (f_{72})_{n}^{−1}]$ configuration. For these levels we got angular distributions from 10° to 70° c.m. We observed that these angular distributions show a typical pattern for each value of the total transferred angular momentum J as shown by levels of ⁴⁸Sc, ⁵²Mn and ⁵⁴Co for which spins are already known. This property allowed us to propose J-values for the more excited levels. Thus, most of the components of the $[(f_{72})_{p} (f_{72})_{n}^{−1}]$ multiplet have been identified in ⁴⁸Sc, ⁵⁰V and ⁵²Mn. For ⁴⁸Sc, angular distributions are practically identical at 18.5 and 30.2 MeV.

It seems that the (³He, t) reaction at 30.2 MeV on N = 28 targets proceeds through an apparently quite simple mechanism.

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 = 52
2015, Nuclear Data Sheets
The nuclear structure data belonging to all nuclei with mass number A=52 have been compiled and evaluated using experimental nuclear reaction data and decay data available before July 10, 2015. This evaluaton supersedes the previous publication for this msss chain (2007Hu08, Nuclear Data Sheets 108, 773 (2007)). The data for the ε decay of ⁵²Co (104 ms) and the ε decay of ⁵²Ni (40.8 ms) are both incomplete, so new studies would be useful.
Nuclear Data Sheets for A = 54
2014, Nuclear Data Sheets
The 2005 evaluation for A=54 (2006Hu08) has been updated. Detailed experimental nuclear structure data and decay data for all nuclei with mass chain A=54 are presented in this current evaluation. The new data and information are given in following datasets:
- ⁵⁴Ca: ⁹Be(⁷⁶Ge, X) and Be(⁵⁵Sc, p), (⁵⁶Ti, 2p)
- ⁵⁴Sc: ⁵⁴Ca $β^{-}$ decay and ⁵⁴Sc IT decay
- ⁵⁴Ti: ⁵⁴Sc $β^{-}$ decay
- ⁵⁴Cr: ⁵⁴Mn ε decay, ⁵⁶Fe(μ, nupng), and ²³⁸U(⁶⁴Ni, Xγ)
- ⁵⁴Mn: ⁵¹V(²⁰Ne, Xγ), ⁵⁵Mn(p, pn), and ⁵⁶Fe(μ, nu2ng)
- ⁵⁴Fe: ⁵⁸Ni α decay, ⁹Be(⁵⁵Co, Xγ), ⁵⁴Fe(e, e'), ⁵⁴Fe(p, p'), and Coulomb Excitation
- ⁵⁴Co: ⁵⁴Ni ε decay, ⁵⁵Cu εp decay, ²⁸Si(³²S, αpnγ), ⁵⁴Fe(p,n), and ⁵⁴Fe(³He, t)
- ⁵⁴Ni: ⁵⁴Ni IT decay, ⁵⁵Zn εp decay, ⁹Be(⁵⁵Ni, Xγ), and ²⁴Mg(³²S, Xγ)
- ⁵⁴Zn: Ni(⁵⁸Ni, X)
Nuclear Data Sheets for A = 50
2011, Nuclear Data Sheets
The experimental nuclear spectroscopic data for known nuclides of mass number 50 (Cl,Ar,K,Ca,Sc,Ti,V, Cr,Mn,Fe,Co,Ni) have been evaluated and presented together with Adopted properties for levels and γ rays. This evaluation has been carried out about 15 years after the previous one by Thomas Burrows (1995Bu29). Except for ⁵⁰Sc and ⁵⁰V, extensive new data have become available for all the other nuclides in the intervening years. The data for ⁵⁰Sc and ⁵⁰V have also been checked again in detail and several changes made. No data are yet available for excited states in ⁵⁰Cl, ⁵⁰Ar and ⁵⁰Ni. This work supersedes earlier evaluations (1995Bu29, 1990Bu18, 1984Al29, 1976Au07) of A=50 nuclides.
