Exploring effective interactions through transition charge density study of70,72,74,76Ge nuclei

Transition charge densities (TCD) for 0⁺ → 2 ₁ ⁺ excitation have been calculated for^70,72,74,76Ge nuclei within microscopic variational framework employing 2p _3/2, 1f _5/2, 2p _1/2 and 1g _9/2 valence space. The calculated TCDs for different monopole variants of Kuo interaction are compared with available experimental results. Other systematics like reduced transition probabilitiesB(E2) and static quadrupole momentsQ(2) are also presented. It is observed that the transition density study acts as a sensitive probe for discriminating the response of different parts of effective interactions.
