Abstract:

A high-spin level structure of the nucleus 154Tm has been established for the first time up to 6.14 MeV. The 118Sn + 40Ca reaction at 205 MeV associated with the recoil shadow method was used to identify the Iπ = (19)+ isomeric state at 2.74 MeV. In-beam γ-ray and conversion electron spectroscopy have been applied on the 144Sm(14N, 4n)154Tm reaction at 95 MeV to build the level scheme. The level structure of 154Tm is compared to other structures observed in N = 85 neighbouring nuclei.
