ELECTRIC MONOPOLE TRANSITIONS AND STRUCTURE OF ~(150)Sm

摘要

The contour plot of the potential energy surfaces V(β, γ) shows that ~(150)Sm is a spherical nucleus and has vibrational characters. The vibrational limit of the interacting boson approximation model (IBA-2) has been applied. Levels belonging to the ground state (g.s), beta (β) and gamma (γ) bands are successfully reproduced. The transition probabilities of gamma transitions are calculated as well as the strength X_(if'f)(E0/E2) of electric monopole, (E0), transitions. The calculated valuesrnare compared with the available experimental and theoretical data. A reasonable agreement has obtained between both.
