High spin states in Ta-170 have been studied via Tb-159(O-16,5n gamma)
Ta-170 reaction through excitation functions, K X-gamma and gamma-gamm
a-t coincidence measurements. Three rotational bands have been identif
ied among which one coupled band and an unfavoured Delta I=2 E2 transi
tion sequence are newly found in this work. The possible quasiparticle
configurations of these bands are discussed.
