Abstract The reaction58Ni→96Ru has been investigated withγ spectroscopic methods and pulsed-beam techniques. A level scheme of the magic nucleus152Yb has been established. The half-life of the isomeric 10+ state was found to be 39±5 μs. The result is discussed in the frame-work of the seniority scheme. Theory and experiment show excellent agreement for the half-lives of the 10+ states in theN=82 isotones148Dy,150Er and [152Yb. A level scheme of151Tm, consisting of ten excited states, has been established.β-decay schemes of [152Yb (3.2±0.3 s),152Tm(m) (8.0±1.0 s) and151Tm (3.8±0.8 s) have been derived. The logft value of theβ transition152Yb (00)→152Tm (1+) has been determined to be about 3.4. It was found that theft values of the favouredβ transitions 0+→1+ in theβ decays of [148Dy,150Er and152Yb are almost inversely proportional to the numbers of protons out of theh 11/2 subshell.
