Decisive role of fragmentation of quasiparticle-phonon configurations in the transition from order to chaos in nuclei
Solov'ev V. G.
The particular excitation energies at which the transition from order to chaos occurs in heavy and intermediate-weight nuclei are determined. It is suggested that a study be made of the fragmentation of many-quasiparticle and quasiparticle-phonon configurations. The fragmentation of three-quasiparticle configurations at the long-lived isomer 178m2Hf—a fragmentation of five-quasiparticle configurations—should be studied in one-nucleon exchange reactions at odd-odd targets, e.g., 176Lu and 180Ta. Analysis of the γ decays of high-spin isomers can yield information on the fragmentation of quasiparticle-phonon configurations.
