M. Elnadi et al., CHARACTERISTICS OF HELIUM FRAGMENTS PRODUCED IN O-16 EMULSION INTERACTIONS AT 960 GEV, Nuovo cimento della Società Italiana di Fisica. A. Nuclei, particles and fields, 107(1), 1994, pp. 1-11
We report the measurements on the partial production cross-section of
helium fragments emitted in the interactions of 60A GeV O-16 ions with
emulsion nuclei. The interaction mean free paths of helium fragments
do not show any anomalous effect at any distance from their production
point. The multiplicity distributions of secondaries are studied as a
function of target components and size. The mean values of the produc
ed shower particles from the interactions of helium beam with light an
d heavy targets are compared with the corresponding values predicted a
ccording to the wounded-nucleon and the collective-tube models.
