Abstract

The relations between wave packet width and projectile fragmentation cross sections are studied in theory by using the improved quantum molecular dynamics (ImQMD) and GEMINI models. The effect of different wave packet width for projectile fragmentation cross sections is analyzed for the reaction ³⁶Ar on C, ²⁰Ne on C, Al, Cu, Sn at 400 AMeV, the isotope distributions with different wave packet width are studied for reactions ³⁶Ar, ⁴⁰Ar on Al. The results show that the projectile fragmentation cross sections are affected by the choice of the wave packet width, and are related to the system of nuclear reaction. The calculation results of σ²_r =2 fm²are in agreement with the experimental results, but the results of σ_r = (0.88+0.09A^1/3) fm have a strong relation with reaction system and the projectile fragmentation cross sections are affected obviously. The influence of wave packet width for ⁴⁰Ar projectile fragmentation cross sections is smaller than that for ³⁶Ar.Moreover isotope distributions with system-size-dependent wave packet width are larger than with σ²_r =2 fm².
