Identification of the $$K^pi=11/2^+$$ isomer in neutron-rich $$^{187}$$W

Shizuma, Toshiyuki; Hayakawa, Takehito; Mitarai, Shiro*; Morikawa, Tsuneyasu*; Ishii, Tetsuro

Physical Review C, 71(6), p.067301_1 - 067301_4, 2005/06

Excited states in neutron-rich $$^{187}$$W have been populated via deep inelastic collisions of a 630-MeV $$^{82}$$Se beam on a $$^{186}$$W target. Projectile-like 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 $$11/2^+$$[615] Nilsson configuration, has been identified with the half-life of 1.56(28) $$mu$$s. The decay rates of the isomers are discussed in terms of the $$K$$ quantum number by comparison with the systematics from the neighboring nuclei.

Excited states in $$^{136}$$Ba, populated in deep-inelastic collisions by the interaction of 450-MeV $$^{82}$$Se ions with a $$^{139}$$La target, have been studied by means of in-beam $$gamma$$-ray spectroscopy. A new isomer with $$I^pi=(10^+)$$ has been identified at an excitation energy of $$E_x=3.357$$ MeV. The half-life was determined as $$T_{1/2}=94pm10$$ ns. The extracted $$B(E2)$$ value is much smaller than those in $$^{132}$$Te and $$^{134}$$Xe. This hindrance is investigated by a shell model calculation.
