Abstract
Decay experiments for148Ho 6− and150Tm 6− were carried out at the GSI On-line mass separator using 5 MeV/A58Ni-beams on94Mo and96Ru targets. Gammaγ-andγX-coincidences established the150Tm 6− decay scheme, and e− gave firm Iπ assignments for148Dy and150Er levels fed in the decays. It was found that the previously unknown 6 −1 state in150Er receives significantβ-strength, which strongly suggestsπh 11/2 νs 2/−11 character for the150Tm 6− isomer. The results are discussed in terms of the expected GT strength function. Shell model calculations for theπh 2/411 yrast states are presented.
