  Transition charge density (TCD) for $ 0^+\to 2_1^+ $ excitation have been
calculated for $\rm ^{70,72,74,76}Ge$ 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 probabilities B(E2) and static quadrupole moments Q(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.
