Analysis of Transverse Momentum Spectra and Rapidity Spectra of Identifiable Particles Produced in 7Be+9Be Collisions
Based on the multi-source thermal model and Landau four-component model,the transverse momentum distributions and rapidity distributions of identifiable particles π±,K±,p and(p)produced by Be+Be at the beam momentum of 19 A,30 A,40 A,75 A and 150 A Gev/c were ana-lyzed by Monte Carlo method,respectively.By contrast of the theoretical calculations and experimen-tal data,the experimental variation trend could be described well by the theory.Therefore,it indicated that the distribution of final-state particles produced in Be+Be collisions system at different beam mo-menta analyzed by the multi source thermal model was feasible.
