摘要：

In the present work, Levy indices mu are measured for target fragments for both ring-like and jet-like events in O-16-AgBr interaction at 60 AGeV and S-32-AgBr interaction at 200 AGeV. The F-q moment analysis reveals unphysical results and hence the Takagi moment analysis is adopted to get an insight into the underlying physical phenomenon. The analysis indicates different degrees of multifractality in the two types of events (ring-like and jet-like) for S-32-AgBr interaction. Also, the Levy stable law is applied to calculate the Levy index mu, which indicates different rates of cascading in different types of events.
