Webthat the mass yield curves in fission are identical among 241 Am, 242111Am, 242gAm and 242 Cm in the thermal or epithermal neutron field, the production cross sections of fission products of 241 Am can be obtained by using the fraction of 241 Am fission in the total fissions. The mathematical procedure is explained in APPENDIX 1. did edmonton win the hockey game last nightWebFission yields from fast-neutron-induced ssion were calculated by a summa- tion method [WA99] giving weighted average parameter values for those model parameters that are energy dependent.
