“…Over the years, the DSM model based on Hartree-Fock states has been used to study with considerable success: (i) spectroscopic properties, such as band structures, shapes, nature of band crossings, electromagnetic transition probabilities and so on in A=64-80 nuclei [15][16][17][18][19][20];…”

Half-lives T 2ν 1/2 for two neutrino positron double beta decay modes β + EC/ECEC are calculated for 84 Sr, a nucleus of current experimental interest, within the framework of the deformed shell model based on Hartree-Fock states employing a modified Kuo interaction in ( 2 p 3/2 , 1 f 5/2 , 2 p 1/2 , 1 g 9/2 ) space. For a reasonable description of the spectra of 84 Sr and 84 Kr and to generate allowed GT strengths, the single particle energies of the proton and neutron 1 g 9/2 orbitals, relative to the 2 p 3/2 orbital energy, are chosen to be (3.5 MeV, 1.5 MeV) for both 84 Sr and 84 Rb and (1.5 MeV, 1.5 MeV) for 84 Kr. With this, the calculated half-lives for the β + EC and ECEC modes are ∼ 10 26 yr and ∼ 4 × 10 24 yr respectively.

“…The model also describes [16] the identical bands in 77,79 Sr, three particle bands [17] in 77,79,81 Br. It has also been successfully applied [18] to odd-odd nuclei 80,82 Br. In view of the above successes, it would be quite interesting to study the 76 Ge → 76 Se double-beta decay within the above microscopic model.…”

The two-neutrino double-beta decay (2νββ-decay) for 76 Ge → 76 Se is studied within the framework of the deformed Hartree-Fock formalism. An interaction given by Kuo and modified by Ahalpara et al is used. The results of our model calculation are compared with those obtained using the shell model and the quasiparticle random phase approximation. The role of the deformation, pairing and Coulomb interaction in double-beta decay is investigated. We have found that the inclusion of both deformation and pairing influences the 2νββ-decay matrix element significantly.

“…Over the years, we have has success using DSM based on Hartree-Fock (HF) states to study spectroscopic properties, such as band structures, shapes, nature of band crossings, and electromagnetic-transition probabilities, for medium-heavy nuclei with A = 64-80 [20][21][22]. More recently, this model was applied to N = Z and N = Z + 1 nuclei by including isospin projection [23,24].…”

Half-lives T 2ν 1/2 for two-neutrino positron double-β decay modes β + EC/ECEC are calculated for 74 Se, a nucleus of current experimental interest, using the deformed shell model based on Hartree-Fock states and employing a modified Kuo interaction in ( 2 p 3/2 , 1 f 5/2 , 2 p 1/2 , 1 g 9/2 ) space. The calculated half-life for the ECEC mode is ∼10 26 yr, and it may be possible to observe this in future experiments.
