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-evapn. reaction were implanted into a silicon detector at the focal plane of a gas-filled separator, where prompt and delayed g-ray transitions were correlated across isomeric states. New states were established upon a known 15 ms isomer in 142Tb and the feeding and decay of a new 0.5(2)ms isomeric state was established in 144Ho. This measurement represents the first observation of excited states in 144Ho. [on SciFinder (R)]
