New microsecond isomers in the neutron-deficient isotopes Bi-189g,Bi-190 ha
ve been identified after in-flight separation by the velocity filter SHIP.
The evaporation residues were identified on the basis of delayed recoil-gam
ma /X-ray, recoil-gamma /X-ray-alpha and excitation function measurements.
The systematics of the [pi 1i(13/2)]13/2(+) excited states in the odd-mass
Bi nuclei is discussed.
