Scissors mode as generated by collective rotation

We have diagonalized the particle-rotor hamiltonian, which includes the recoil term and the Coriolis interaction, in a realistic, large space and obtained eigenfunctions for Iπ = 0+ and 1+. We have calculated B(M1 : 0+g.s. → 1+) and the overlap integral of the Iπ = 1+ states with the scissors mode wave function. It was found that the recoil term works to generate a collective state which has a large value of B(M1 : ↑) and appreciably overlaps with the scissors mode. It is found also that no rotational bands develop on most of the 1+ levels which heavily involve h211/2 or i213/2 configurations. (orig.)
