Název v původním jazyce

Low-lying levels of Re-188 nucleus from gamma gamma-coincidence measurements

Popis výsledku v původním jazyce

Low-high and low-low energy gamma gamma-coincidences, following the Re-187(n, gamma) Re-188 reaction with thermal neutrons, have been measured. Spectra have been recorded in the energy range from 50 to 2600 keV, and from 4500 to 6500 keV. The earlier known Re-188 level scheme is corrected and extended up to similar to 800 keV excitation energy and 62 levels by including 20 new levels. For 11 levels, the earlier interpretation has been changed. The complete level scheme is presented for up to similar to400 keV energy and spins <= 5. Core plus two-quasiparticles model calculations have been performed. Some Re-188 two-quasiparticle states display features indicating the nuclear shape phase transition from axial-deformation to gamma-soft form.
