Identification: genetic relationship of 1.4-min activity from 176Yb(n,α) to known radiations from 173Tm, cross bombardments (natural and enriched targets) (1972Pu02).
α 1.9-min activity, previously assigned to 173Er (1960Wi10), was reassigned to 176Tm (1970Tu07).
The properties of a 12-min activity, previously assigned to 173Er (1968Ih01), are very different from those attributed to 173Er by 1972Pu02. The 12-min activity probably includes contaminants, and remains unassigned.
Q-value: Note: Current evaluation has used the following Q record 2600 SY5240 syst 1993Au05,1993Au07
