An effort has been made to search for the decoupled bands in odd-odd Re-174
via the Tb-159(Ne-20,5n gamma)Re-174 reaction through excitation functions
, K x-gamma and gamma-gamma coincidence measurements. The doubly decoupled
band and the semidecoupled one have been found in this work. Their quasipar
ticle configurations are proposed to be pi 1/2(-) x upsilon 1/2(-)[521
] and pi 1/2(-)x upsilon i(13/2), respectively, according to the chara
cteristics of band structures in this mass region. Another band with strong
ly coupled character is also reported.
