Nuclear data sheets for A = 174

摘要: Abstract The 1965 version of the Nuclear Data Sheets for A = 174 has been revised on basis experimental data received prior to May 1, 1972. Nine nuclei are known 174. Only α-decays and half-lives Os, Ir, Pt. Consistent decay schemes Tm, Lu, 142-d 174m levels in Yb, Hf, W from reaction studies presented. (e+β + )-decay Ta is not well known, presumably because competition decays 175 176 Ta. number states Hf this decay, however, consistent with established studies. Study isotope-separated activity would probably remove uncertainties present data.
