Rotational bands in 181 Ta

High-spin states in 181 Ta have been studied via the 176 Yb( 11 B,fi2n) reaction at 52 MeV using the PEX array and at 57 MeV using the NORDBALL array, with fi-particle detection. The previously known, K … = 7 + ground state band and K … = 9 i band have been extended to spins 29 2 + and 31 2 i ,
