摘要
An investigation on the presence of ring and jet-like structures is carried out in the angular emission of target-evaporated slow particles emitted in O-16-Ag/Br interactions at 60 A GeV/c and S-32-Ag/Br interactions at 200 A GeV/c. The nuclear emulsion technique was employed to collect the experimental data. We compared our experimental results with those obtained from Monte Carlo simulations. The analysis indicates the presence of ring and jet-like structures in the experimental data beyond the statistical noise. The presence of ring-like structure is fairly pronounced in O-16-Ag/Br interactions compared to S-32-Ag/Br interactions and jet-like structure is more distinct in S-32. One dimensional (1d) intermittency for ring-like structures and two dimensional (2d) intermittency for jet-like structures are expected. The self-affine behavior of 2d scaled factorial moments (SFM) were investigated and the strength of 2d intermittency was determined. For each set of data, the 2d results were compared with the corresponding one-dimensional (1d) intermittency results. The strength in 2d is significantly greater than Id for S-32-Ag/Br interactions whereas for O-16-Ag/Br interactions 1d is greater than 2d. This is also a sign of predominance of jets in S-32-Ag/Br and the rings in O-16-Ag/Br interactions.
