Abstract：
A new transport model (isospin dependent Boltzmann-Langevin equation)is developed and it is shown that this model can regenerate the experimental data for reaction of ¹²C+ ¹²C at 28.7MeV/u. The production cross section of ¹⁹Na is systematically studied for reactions of ^17—20,22Ne+ ¹²C at 28.7 MeV/u.It is found that a neutron deficient projectile has larger ¹⁹Na cross section than a stable projectile.
