Excited states in neutron-rich {sup 187}W have been populated via deep inelastic collisions of a 630-MeV {sup 82}Se beam on a {sup 186}W target. Projectilelike fragments were measured by an annular Si detector for reaction channel selection. Delayed {gamma} rays from target residues were detected by means of the so-called recoil shadow technique. A new isomer at 411 keV, based on the 11/2{sup +}[615] Nilsson configuration, has been identified with a half-life of 1.55(13) {mu}s. The decay rates of the isomers are discussed in terms of the K quantum number by comparison with the systematics from neighboring nuclei.
