Study of Production of Secondary Beams from 95MeV/u 12C Projectile

A systematic study about the production of secondary beams in 95MeV/u ¹²C+Be,Cu and An targets was performed by using the GANIL doubly achromatic spectrometer LISE.The maximum values of the secondary beam production calculated by programs LISE and INTENSITY are in agreement with the experimental results for the secondary beams near the β stability line.However,the calculations are larger than the experimental results for the secondary beams far from the β stability line.The optimum target thickness for the production of secondary beams corresponds to about 30% beam energy loss in the target.Beryllium target was found to offer higher production for all the secondary beams than copper and gold targets.
