[en] Nuclides with A = 152 were produced in /sup 58/Ni bombardments of /sup 96/Ru and their decay properties were investigated following on-line mass separation. The isotope /sup 152/Lu (T/sub 1/2/ = 0.7 +- 0.1 s) was identified by γ rays in its β-decay daughter, /sup 152/Yb. Based on its decay characteristics, the parent state has a probable spin and parity assignment of (4,5,6^-). Several new transitions were observed to follow the β decays of /sup 152/Yb and the /sup 152/Tm low-spin isomer; they established previously unknown levels in both /sup 152/Tm and /sup 152/Er. The additional γ rays in /sup 152/Yb decay reduce from 100% to 88% the direct feeding to the one excited state in /sup 152/Tm that had been known earlier. Nevertheless, the corresponding logft value is calculated to be 3.5, indicating that this is an allowed β transition which connects the 0⁺ parent with a 1⁺ excited state in /sup 152/Tm. By comparing the β-decay rates of /sup 148/Dy and /sup 152/Ho, and the α- and β-decay rates of /sup 152/Er, an α branch of 90 +- 4 % was deduced for /sup 152/Er
