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