“…In the special cases of electric monopole, quadrupole and hexadecapole transitions, the specific form of the transition operator is respectively, γ 0 , α 2 and β l (l = 0, 1, 2, 3, 4) which are parameters specifying the various terms in the corresponding operators. Then the electric quadrupole transition is (Motelb, 2012;Hussain et al, 2017):…”
