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