Abstract
A new isotope152Tm (T 1/2=5.2±0.6 s) and a new isomeric state in150Ho (T 1/2=88±15 s) were observed with the on-line isotope separator ISOCELE II at Orsay. The decay of152Tm is similar to the one of the high spin state (9+) in150Ho. The new150Ho isomer, probably with a low spin (2 or 3), decays mainly to the 2+ level in150Dy.
