Findings

Improved agreement with ALADiN experimental data.

Enhanced accuracy over traditional MST method.

Validation against simulated annealing results.

Abstract

We study the formation of fragments by extending the minimum spanning tree method (MST) for clusterization. In this extension, each fragment is subjected to a binding-energy check calculated using the modified Bethe-Weizsacker formula. Earlier, a constant binding-energy cut of 4 MeV/nucleon was imposed. Our results for 197Au +197 Au collisions are compared with ALADiN data and also with the calculations based on the simulated annealing technique. We shall show that the present modified version improves the agreement compared to the MST method.
