Abstract. Levels in t74Hf excited in the decay of ~V4Ta have been studied. Measurements of gamma-rays, conversion electrons and gamma-gamma-time coincidences were performed. The ground state band, the beta-vibrational band, the gamma-vibrational band with its head at 1226.81keV, a K=3 + band at 1303.42keV and a K=2-octupole band at 1308.67 keV were observed. Several 2 + levels with K -0 are excited. The main fl+-branches proceed through allowed or first-forbidden transitions to the 2 + and 4 + levels of the ground state band. The character of the I" = 3 ~ +) ground state of 174Ta is discussed. E Radioactivity 174Ta I-from 175Lu(3He, 4n)
