PRELIMINARY RESULTS ON INTERACTIONS OF PS PROTONS IN NUCLEAR EMULSIONS

1960 
S>Tracks of PS protons Mean enengy of 21 Rev) in nuclear emulsions were followed, and 491 reactions with nuclei were found. A mean free path of 37.8 plus or minus 2.7 cm for the star products was determined. The frequency distribution of the stars as a function of the number of the grey and black tracks emitted was compared with the frequency distribution obtained at 6.2 Bev. The comparison indicated that the number of evaporation tracks is practically independent of the primary energy between 6 and 24 Bev. Of all interactions 12.4% appear as so-called white stars, which are stars with only rare secondary tracks. The frequency distribution of white stars was determined as a function of the number of their charged secondary tracks. The angular distribution of the secondary track in the L system was measured against the primary direction. (J.S.R.)
