Double beta decay (DBD) is clear sign of new physics beyond the standard model. Depending on the relative number of protons and neutrons in a nucleus, the three additional possible processes are double electron capture (ECEC), double positron decay (β+β+) and positron emitting electron capture (ECβ+). These three processes are energetically competing and are referred as positron double beta decay (e+DBD) modes. While DBD has been observed in about a dozen nuclei, the e+DBD modes continue to be an elusive. The study of these modes require the knowledge of nuclear transition matrix elements (NTMEs), therefore, in this work, we have considered the nuclei namely 58Ni, 74Se, 78Kr and 112Sn, and studied their spectroscopic properties such as yrast energies, quadrupole moment (Q), magnetic moment (μ) and reduced transition probabilities B(E2). The obtained values are then compared with available experimental data to check the reliability of the wave functions. These wave functions may then be used for calculation of NTMEs for these positron double beta decay modes.
