Abstract：
Within the Boltzmann-Langevin equation , the neutron cluster production cross sections in the reactions induced by ¹⁴Be, ⁸He,⁶He,¹¹Li,¹⁷B,¹¹Be,¹⁹C on ¹²C at 35MeV/u were studied. The experimental data for ⁴n production cross section from ¹⁴Be+¹²C at 35MeV/u can be reproduced. It is found that the production cross section of neutron cluster is large in the reaction that the projectile has more halo nucleons. And the projectiles with big mass number are easy to produce the neutron cluster, when they have the same number of halo nucleons. The neutron cluster is probably mainly from the halo nucleons of projectile.
