The values of the total charge-changing cross section are σtot=(11794-50) mb and σtot=(11864-42) mb at 736 and 723A MeV, respectively. The result is compared with the ones obtained by other experimental and theoretical results. The odd-even effect of the partial charge-changing cross section is observed.展开更多
