摘要

Gamma rays from the decay of an isomer in ~(190)W_(116) have been observed following projectile fragmentation of a 1 GeV per nucleon ~(208)Pb beam. An earlier experiment indicated decay from a (10~-) isomer to the ground state rotational band. Improved statistics have enabled gamma coincidence and time-difference measurements to be made which alter the previous interpretation. Blocked BCS calculations have also been used together with reduced hindrance factors to indicate possible values of spin-parity for the isomer.
