A SCHEMATIC MODEL FOR THE STUDY OF FRAGMENTATION OF SCISSORS M1 STRENGTH IN DEFORMED-NUCLEI

We study a fragmentation model in order to describe the distribution o f a collective, scissors-like 1(+) state into a background of deformed two- and four-quasiparticle excitations. The coupling matrix elements for coupling the collective state to the underlying microscopic struc tures are studied. The fragmentation results are compared to the avail able data. One-nucleon transfer strength distributions are discussed w ith reference to the fragmentation of two-quasiparticle configurations . We also point out possible origins for intermediate structure in the fragmentation mechanism.
