Abstract

Postaccelerated58Ni beams from the Munich tandem have been used to study the residual activities of the compound reactions58Ni→90Zr,91Zr,92Zr,93Nb,92Mo,94Mo with the help ofγ excitation functions, multi spectrum analyses ofγ radiation,γγ coincidences and the measurement of the ratio EC/gb +. Beta decay schemes for the following new isotopes or isomers have been derived:144Tb (6, 7) 4.5±0.5 s144Tb 1+ 1.5±1 s145Tb (11/2) 29 s146Tb 1+ 8±4 s145Dy 13.6±1 s146Dy 0+ 29±3 s147Ho (11/2) 5.8±0.4 s148Ho 1+ 2.2±1.1 s150Ho (2) 72±4 s148Er 0+ 4.5±0.4 s150Er 0+ 18.5±0.7 s148TmJ≧6 0.7±0.2 s150Tm (4, 5) 3.5±0.6 s

TheQ EC value for theβ decay of150Er to150Ho has been measured to be 4,010±80 keV with respect to the 2 state in150Ho.
