摘要:

The massA= 140 products of the54Fe (315 MeV) +92Mo reaction were selected by a recoil mass spectrometer and studied in a recoil ‐ delayed &ggr;‐&ggr; coincidence experiment. A new 7 &mgr;s isomer was identified in the drip line nucleus140Dy. Five cascading &ggr; transitions were assigned to the decay of theI&pgr;= 8−{v9/2−[514] ⊗v7/2+[404]}Kisomer via the ground state band transitions. The established structure of140Dy is discussed with reference to the fine structure in proton decay of141Ho. © 2003 American Institute of Physics
