摘　　要：对3.7AGeV16OEm作用产生的α射弹碎片多重数分布进行了研究,得出电磁离解作用和核作用下α射弹碎片的分布服从不同的函数,说明在两种作用下碎片的产生机制不同.The multiplicity distribution of helium projectile fragments produced in 16O-Em at 3.7 A GeV is investigated. It is found that the multiplicity distributions of alpha fragments in electromagnetic dissociations and nuclear events have different functional form. This difference may be a consequence of the different reaction mechanisms involved in electromagnetic dissociations and nuclear events.
