Excited states in drip line nucleus 140Dy

A new 7 μs isomer in the drip line nucleus 140Dy was selected from the products of the 54Fe (315 MeV) + 92Mo reaction by a recoil mass spectrometer and studied with recoil ‐ delayed γ‐γ coincidences. Five cascading γ transitions were interpreted as the decay of an Iπ = 8− {v9/2−[514] ⊗ v7/2+[404]} K isomer via the ground state band.
