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 $T_{1/2} = (2.6 \pm 0.5)$ ns at an excitation energy $E_{\rm x} = 9232$ keV seems to belong to a family of isomers of similar configuration in neighbouring N = 82 nuclei.
