In order to study effects of clustering of colliding nuclei in the fragmentation process, the fragmentation of the 14N+ 12C reaction at 35 MeV/nucleon is analyzed by antisymmetrized molecular dynamics. It is found that 4He fragments from 12C fragmentation are much more abundant than those from 14N fragmentation. Characters of 4He fragments from 12C fragmentation are investigated and it is found that this abundance in 12C fragmentation results from the three-alpha breakup in a short time scale where the excited states with excitation energy 7-15 MeV play an important role.
