Precision measurement of ICCs of some pure E2 transitions for comparison with BRICC calculations

There are specific problems to overcome in decay data analysis; in particular, difficulties can arise in accounting for internal conversion when the internal conversion of a gamma ray transition is significant. If there are no experimental ICCs available, theoretical ICCs have to be adopted, and the evaluator is faced with having to choose a value from a number of comparable theoretical approaches. Hence it is of paramount importance to have both very precise experimental ICCs and also to know the accuracy with which any theoretical ICC can be accepted to use
