摘要: A new high-spin isomer in 150Dy has been observed at an excitation energy of 10.3 MeV by combining the inverse-kinematic reaction induced a pulsed beam 132Xe and $\gamma$ -ray recoil-shadow technique. The half-life this isomeric state determined to be $T_{1/2} = 1.6 \pm 0.6$ ns using conventional centroid-shift method with 141Pr(16O, p6n)150Dy 165 MeV. mechanism producing isomers N 83,84 isotones is qualitatively discussed terms difference neutron particle-hole configuration between lower-lying state.
