Level structure in the transitional nucleus Fr 215

Popis výsledku v původním jazyce

The level scheme of Fr215 is extended up to 55/2 ℏ and 4.8 MeV excitation energy with the addition of 52 new γ-ray transitions. Previously established isomers and their half-lives, except for the 47/2+ state, are revisited. The discrepancy in the half-life of the 39/2- state is resolved, and its half-life is revised to 11.4(14) ns. An overall good agreement is observed between the experimental results and the shell-model calculations performed using the CD-Bonn NN interaction derived from the Vlow-k renormalization approach. A weak coupling of the odd proton to the even-even core is observed to account for the level structure at lower energies, which strongly resembles a decoupled nonrotational band. A new positive-parity sequence is also established which is observed to originate from the coupling of the i13/2 proton at low excitation energy.
