The (t, p) reaction on the zinc isotopes

The doubly even isotopes of Zn and Ge have been investigated in a model in which two quasiparticle excitations, constructed in a (0f7/2), lp3/2, Ofs/2, lpl/2,099/2 configuration 4-0 56 space, are coupled with quadrupole vibrations of the core, viz. Ca or Ni. The 0f7/2 orbit is excluded in case of a 56Ni core. The spectra, except for low-lying excited 0 + states, could be reproduced reasonably well. The calculated E2 strengths and quadrupole moments are in fair agreement with experiment.

“…A half-life of 6.6(1) s and a partial decay scheme toward excited states in the daughter nucleus 72 Zn were reported. Additional information on the nuclear structure of 72 Zn results from an earlier 70 Zn(t, p) 72 Zn transfer reaction work by Hudson and Glover [11] and from multinucleon transfer reactions performed recently by Wilson et al [12]. 72 Ni was first identified by Armbruster et al in the thermalneutron-induced fission of 235 U [13].…”

“…In the previous β-decay study of 72 Cu by Runte et al [10], the spin and parity of the excited states at 653, 1499, and 1658 keV were adopted from the 70 Zn(t, p) 72 Zn reaction work of Hudson and Glover [11]. In the latter, excited states at 652 (10), 1505 (10), and 1652 (10) keV were observed and I π assignments of 2 + , 0 + , and 2 + were made by comparing the experimental (t, p) cross sections with optical model TABLE II.…”

The β-decay properties of 72 28 Ni 44 and 72 29 Cu 43 have been studied at the LISOL facility of Louvain-La-Neuve and at the CERN-ISOLDE facility, respectively. These neutron-rich nuclei have been produced in the proton-induced fission of 238 U. Their decay schemes are presented and the lifetime T 1/2 = 6.63(3) s of 72 Cu was measured. No β-decaying isomeric state was found in 72 Cu, in line with a suggested spin (2) for its ground state. Spin and parity assignments of the observed excited states in the odd-odd nucleus 72 Cu are proposed and discussed in terms of coupling between the valence proton and neutrons. Comparison is made with a schematic shell-model picture of 72 Cu and with large-scale shell-model calculations performed in the (2p 3/2 1f 5/2 2p 1/2 1g 9/2 ) shell space outside the doubly magic 56 28 Ni 28 core.

“…The spin and parity assignment of several excited states in 72 Cu is partly derived from a comparison with earlier works of Runte et al [7], Hudson and Glover [11] and Wilson et al [12]. More details will be available in [6].…”
