Angular Distribution for sup 56 Fe( Pi sup + , pi /sup /minus//) sup 56 Ni(DIAS) (Double Isobaric Analog State).

摘要

We have measured a ( pi sup + , pi /sup /minus//) angular distribution for the transition to the double isobaric analog state of a T = 2 target nucleus, sup 56 Fe, at T/sub pi / = 180 MeV. The data are compared to measurements on T = 1 targets and to theoretical predictions. The angular dependence is different from that observed in measurements on T = 1 targets. Some features of the data are reproduced by the theoretical predictions, but significant discrepancies remain. 15 refs., 3 figs., 1 tab. (ERA citation 14:021166)
