Eighteen new isomers have been observed in a pulsed 15-MeV deuteron beam survey of 72 elements. Gamma-ray transitions were observed using time and energy channels in a two-dimensional 4096-channel analyzer. The new isomers are: Eleven isomers previously reported were confirmed, and in some cases, further information on them was obtained.
