Isomeric states in the neutron-rich nuclei 111Zr [T1/2=0.10 (7) μs] , 113Nb [T1/2=0.7 (4) μs], 115Mo [T1/2=46 (3) μs] were first identified at the Radioactive Ion Beam Factory (RIBF) of RIKEN by using in-flight fission and fragmentation of a 238U beam at an energy of 345 MeV/u. Here is a brief report of the γ transitions de-exciting from isomeric states and half-lives measurements, which provides the first spectroscopy in the nuclear region of prolate-to-oblate shape-phase transition around mass A ≈110.
