摘要
The pseudo SU(3) model is used to study the double-beta decay of Nd-150 to the ground and excited states of Sm-150. Low-lying collective excitations of Sm-150 and its BE(2) intensities are well reproduced. Expressions for the nuclear matrix elements of the two-neutrino double-beta decay to excited states are developed and used to describe the decay of Nd-150. The existence of selection rules which strongly restricts the decay is discussed.
