Abstract
We have investigated the beta decay of the T = 0, T(1/2)approximate to2.2 s , isomeric level in the self-conjugate odd-odd nucleus Br-70. The observed beta -delayed gamma rays in the daughter nucleus Se-70 and the deduced deca y properties of the isomeric level allow, in conjunction with results from the deformed shell model, a spin and parity assignment of J(pi) = 9(+) and suggest a structure of {pi [404]9/2(+) nu [404]9/2(+)}9(+). The allowed unh indered beta decay of the isomer, possibly oblate deformed, proceeds to fou r-quasiparticle states in Se-70.
