Abstract

This contribution discusses the recoil-isomer tagging technique and its application to study isomeric states near the mass 140 proton drip line. The recoiling nuclei from a fusion-evaporation reaction were implanted into a silicon detector at the focal plane of a gas-filled separator, where prompt and delayed γ-ray transitions were correlated across isomeric states. New states were established upon a known 15μs isomer in 142Tb and the feeding and decay of a new 0.5(2)μs isomeric state was established in 144Ho. This measurement represents the first observation of excited states in 144Ho.
