摘要: Abstract Proposed is a model in which particles the intruder orbitals couple to soft rotor. The number of not fixed but allowed take on various values through pairing field. rotor described by making use coherent boson states from angular momentum eigenfunctions are projected out. Calculations made for 158 Er and experimental energy spectra B (E2) well reproduced.
