Yrast traps were found in N=83 isotones, 144Pm and 145Sm, by using inverse kinematic reactions, 14N(136Xe, 6n)144Pm and 16O(136Xe, 7n)145Sm. Their probable spin-parities are (27+) and ( 49 2+), respectively. Excitation energies of these isomers are 7.5 and 8.7 MeV Reaction products were transported by a gas filled recoil ion separation system and collected at 6 m down stream of the primary target position . The possible utilization of these high-spin isomers as secondary beams are discussed.
