REVISION OF THE K-ISOMER IN 190W116.

Gamma rays from the decay of an isomer in ¹⁹⁰W₁₁₆ have been observed following projectile fragmentation of a 1 GeV per nucleon ²⁰⁸Pb 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. [ABSTRACT FROM AUTHOR]
