A systematic dependence of Grodzins product (E(2+1) * B(E2)↑) on the asymmetry parameter Υ0 is studied in the Z = 50 − 82, N = 82 − 126 major shell space. The Grodzins product provides contributions of E(2+1) and B(E2) " simultaneously, which further reflects the shape
phase transitions with asymmetry parameter 0. In the region of deformed nuclei, Grodzins product (E(2+1)*B(E2)↑)
shows direct dependence on the asymmetry parameter 0. We discuss here for the first time the correlation between
Grodzins product (E(2+1) * B(E2)↑) and the asymmetry parameter Υ0.
