Ht. Fortune et al., ENERGY-DEPENDENCE OF CROSS-SECTIONS FOR PION DOUBLE-CHARGE-EXCHANGE ON NI-60,NI-62,NI-64, Physical review. C. Nuclear physics, 55(5), 1997, pp. 2468-2470
Double charge exchange cross sections have been measured at theta(L) =
5 degrees and T-pi = 230, 180, and 140 MeV for targets of Ni-60,Ni-62
,Ni-64. Results are compared with previous data at 292 MeV and with a
generalized seniority model.
