“…No restriction has been put on the number of particles which can be excited to higher levels. Similar calculations for even isotopes of 62−66 Fe and odd isotopes of 61−65 Fe were performed by us and have been reported in the literature [10,11]. The f pg 9/2 model space comprises of the 0f 7/2 , 1p 3/2 , 0f 5/2 , 1p 1/2 active proton orbitals and 0f 7/2 , 1p 3/2 , 0f 5/2 , 1p 1/2 , 0g 9/2 neutron orbitals with eight 0f 7/2 frozen neutrons.…”

Large scale shell model calculations have been carried out for odd-odd 58−62 Mn isotopes in two different model spaces. First set of calculations have been carried out in full fp shell valence space with two recently derived fp shell interactions namely GXPF1A and KB3G treating 40 Ca as core. The second set of calculations have been performed in f pg 9/2 valence space with the f pg interaction treating 48 Ca as core and imposing a truncation by allowing up to a total of six particle excitations from the 0f 7/2 orbital to the upper fp orbitals for protons and from the upper fp orbitals to the 0g 9/2 orbital for neutron. For low-lying states in 58 Mn, the KB3G and GXPF1A both predicts good results and for 60 Mn, KB3G is much better than GXPF1A. For negative parity and high-spin positive parity states in both isotopes f pg interaction is required. Experimental data on 62 Mn is sparse and therefore it is not possible to make any definite conclusions. More experimental data on negative parity states is needed to ascertain the importance of 0g 9/2 and higher orbitals in neutron rich Mn isotopes.

“…Following our recent shell-model (SM) studies for neutron-rich even isotopes of Fe [5], odd-odd Mn isotopes [6], and odd-mass 61,63,65 Co isotopes [7], in this paper we report large scale shell model calculations for 71−78 Ga isotopes. Earlier shell model calculation using pairing plus quadrupole-quadrupole interaction for 75,77,79 Ga isotopes have been reported by Yoshinaga et.…”

We have performed comprehensive set of shell model calculations for Ga isotopes including high-spin states with three different effective interactions. This work will add more information in the earlier work by Cheal et al. for odd-even Ga isotopes [ Phys. Rev. Lett. 104, 252502 (2010)] and Mané et al. for odd-odd Ga isotopes [ Phys. Rev. C 84, 024303 (2011)], where only few excited states are studied in f 5/2 pg 9/2 space. For lighter isotopes f pg interaction is better and for heavier isotopes jj44b is quantitatively better than JUN45. These results show that limitation of existing interactions and calling for further improvements to predict nuclear structure properties of Ga isotopes.

We have interpreted recently measured experimental data of 77 Ge, and also for 73,75,79,81 Ge isotopes in terms of state-of-the-art shell model calculations. Excitation energies, B(2) values, quadrupole moments and magnetic moments are compared with experimental data when available. The calculations have been performed with the recently derived interactions, namely with JUN45 and jj44b for f 5/2 pg 9/2 space.We have also performed calculation for f pg 9/2 valence space using an f pg effective interaction with 48 Ca core and imposing a truncation to study the importance of the proton excitations across the Z = 28 shell in this region. The predicted results of jj44b interaction are in good agreement with experimental data. * Email: praveen.srivastava@nucleares.unam.mx 1. W. Rother et al., Phys. Rev. Lett. 106, 022502 (2011). 2. N.
