Lifetimes and structures of some levels above 1.5 MeV in $sup 168$Yb, $sup 164$Er, and $sup 158$ $sup 160$ $sup 162$Dy

Technical Report ·
OSTI ID:4932735
The following lifetime measurements were performed in /sup 168/Yb: 62ns (7/sup -/, 2222.5 keV); 0.34ns (6/sup -/, 211l.1 keV) 81.7n s 5/sup -/, 1998.7 keV); <=0.14ns (4/sup +/, 2203.8 keV); in /sup 164/Er: 23.3n s 7/sup -/, 1985.0 keV); 0.22ns (6/sup -/, 1744.4 keV); <=0.08ns (5/sup -/, 166 keV); in /sup 158/ Dy: <=0.11ns (4/sup +/, 1895.3 keV); in /sup 160/Dy: O.18ns (4/sup +/, 94.0 keV); in /sup 162/Dy: 1.93ns (5/sup -/, 1485.9 keV). The experimental reduced transition probabilities are discussed in the framework of current nuclear models. (FR)
