| 英文摘要 | We report on the first gamma-ray spectroscopy of low-lying states in neutron-rich Kr-98,Kr-100 isotopes obtained from (99,101)Rbd (p,2p) reactions at similar to 220 MeV/nucleon. A reduction of the 2(1)(+) state energies beyond N = 60 demonstrates a significant increase of deformation, shifted in neutron number compared to the sharper transition observed in strontium and zirconium isotopes. State-of-the-art beyond-mean-field calculations using the Gogny D1S interaction predict level energies in good agreement with experimental results. The identification of a low-lying (0(2)(+),2(2)(+)) state in Kr-98 provides the first experimental evidence of a competing configuration at low energy in neutron-rich krypton isotopes consistent with the oblate-prolate shape coexistence picture suggested by theory. |
