“…A K = 3, 2 assignment for these levels can be deduced from comparison of the gamma-ray branching ratios with the Alaga rule. Similar levels with K =3 + are observed in l V6Hf close to the gamma-vibrational state [17]. The most probable two-quasi-particle configuration for this band is n [51231" + n [521 ] ~.…”

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)

We have identified several high-K four-and six-quasiparticle states between 2 0 5 and 5 MeV excitation in 176 Hf, which are well described by the collective model with axial symmetry,, Isomers with K n = 14", 19 + , and 22" form traps at or near the yrast line. The yrast structure changes from the ground band to a K v = 16 + band at J = 16 and again to a K n =22" state at 7 = 22, providing the first demonstration that intrinsic excitations of a heavy deformed nucleus can become yrast.An etch parameter almost unnoticed previously, etch induction time, has been measured in Kodak Pathe cellulose nitrate track detector films using 4 He, 6 Li, 12 C, 14 N, and le O ions of known low energy per unit mass for calibration. The etch induction time appears to vary with the parameter (dE/dx) w< im /Z* where Z* is the effective ion charge and (dE/ dx) w< 1000 is the restricted energy loss, calculated for a S-ray cutoff energy of 1000 eV.
