ON THE VALIDITY OF THE CHFB METHOD FOR TREATING THE CSM HAMILTONIAN

    Corresponding author: PENG Jian-Ping,
  • Peking University

Abstract: The accurate solutions for the low-lying eiginvalues and eigenstates of the single-j CSM hamiltonian have been obtained and are compared with the HFB approximation.There exist a world of difference between the two,especially the behaviour of the yrast and the yrare bands near the bandcrossing and the band interaction strength.The theoretical foundation of the CHFB method for treating the rotating nuclei needs reexamination.
