Analysis of momentum distributions of projectile fragmentation products Original Research Article

A model describing fragment momentum distributions as a function of the projectile energy has been developed. This model called “Universal parameterization” is based on the convolution between a gaussian distribution corresponding to Goldhaber model of fragmentation and an exponential attenuation arising from friction between projectile spectator and participant. An analysis of several experimental data sets has been performed to obtain the coefficients of the Universal Parameterization in order to avoid drawbacks inherent to the fragmentation statistical model. The Universal parameterization is incorporated in the LISE++ code for fragment transmission calculations.
