Abstract
The reactions58Ni+102Pd→160W and58Ni+106Cd→164Os were investigated to search for new decay data of neutron deficient nuclei. Excitation energies of the compound nuclei covered a range from 47 to 89 MeV. Velocity separation of the evaporation residues and position time correlations with the a decays of the implanted nuclei were used. The following new decay data were measured:162Os (Eα=(6611 ±30) keV, T1/2=(1.9±0.7) ms);158W (T1/2=(0.9±0.3) ms);158mW (E=1.88 MeV, Eα=(8280±30) keV, T1/2=(0.01-1) ms);155mLu (Eα=(5575±10) keV); β decay of156Ta (T1/2 > 10 ms) to the 8+ yrast isomer in156Hf. A cross section of 5μb was measured for the new isotope156Ta produced in a p3n evaporation channel from160W at 64 MeV excitation energy.
