Abstract
The theme of present analysis is to focus on the emission characteristics of grey particles emitted in 4π angle, forward hemisphere angle (θ < 90°) (FHS) and backward hemisphere angle (θ ≥ 90°) (BHS). We have studied the average multiplicity variation of grey particles for the events emitted from the reaction of projectiles with CNO and AgBr target nuclei of nuclear emulsion. We have also investigated the emission probability of grey particles with projectile mass in between the range of 1 and 207. In this analysis we have observed that the emission probability of grey particles is higher in forward hemisphere angle as compared to backward hemisphere angle. We have also observed that the average multiplicity of grey particles is independent on the projectile mass and incident energy.
