4.5 AGeV/c 16O-AgBr作用慢粒子间歇行为

A study on intermittency of slow particles produced in the interactions of 16O-AgBr at 4.5 AGeV/c with nuclear emulsion using the method of factorial moments, F(subscript q), was performed. The dependence of the moments on the number of bins M was found to follow a power law behavior for the experimental data in terms of new scaled variable χ(cos θ). The results show that the intermittency exponent increases with the increase of moment order, and the generalized dimensions D(subscript q) decreases with the increase of moment order, q. This observation indicates the association of multifractality with production mechanism of slow particles.
