Abstract
The influence of hyperfine interactions (deorientation of the nuclear angular momentum) on the results obtained by means of coincidence RDDS measurements is investigated. It is analytically shown that if the da ta are analyzed with the differential decay curve method (DDCM) the li fetimes derived are not affected by the deorientation provided the gat es are set on transitions which feed directly the level of interest. W ith gates set higher in the cascade, the arising error is expected to be rather small.
