Abstract

Isomeric states in ^59,61 Ti have been populated in the projectile fragmentation of a 345 AMeV ²³⁸ U beam at the Radioactive Isotope Beam Factory. The decay lifetimes and delayed γ-ray transitions were measured with the EURICA array. Besides the known isomeric state in ⁵⁹ Ti, two isomeric states in ⁶¹ Ti are observed for the first time. Based on the measured lifetimes, transition multipolarities as well as tentative spins and parities are assigned. Large-scale shell model calculations based on the modified LNPS interaction show that both ⁵⁹ Ti and ⁶¹ Ti belong to the Island of Inversion at N=40 with ground state configurations dominated by particle-hole excitations to the g _9/2 and d _5/2 orbits.
