Abstract:

Using the single j-shell model with the pairing plus quadrupole force, we show that
1) the transition from vibrational to rotational excitation structure can be reproduced within the collective model space built up from the J = 0- and J = 2- coupled nucleon pairs,
2) change of the monopole pair field due to many-quasiparticle excitations does accelerate the transition; this fact indicates the importance of taking explicit account of the coupling between pairing rotation and many-phonon excitations in transitional nuclei.
