Abstract: An in-beam experiment with the reaction ¹²²Sn(²⁷Al,4np) at 127 MeV was performed at the Nordball multi-detector array in Roskilde. It provided evidence for a new high-spin isomer in ¹⁴⁴Sm. This isomer with T_1/2 = (2.6 ± 0.5) ns at an excitation energy E_x = 9232 keV seems to belong to a family of isomers of similar configuration in neighbouring N = 82 nuclei.
