基于同位旋相关量子分子动力学研究了中子晕核和质子晕核的核反应动力学，着重研究了松散的晕结构对于重离子碰撞中的碎裂和动量耗散中的特殊作用。

We studied systematically the reaction dynamics induced by neutron-halo nuclei and proton-halo nuclei within the isospin dependent quantum molecular dynamics , such as the effects of loose bound halo-nuclei on the fragmentation reaction and momentum dissipation for different colliding systems with different beam energies and different impact parameters .

通过计算与分析可知：有较大份额的中子和光子直接从质子束管中泄漏出去，且泄漏的中子和光子的能量相当高；

The fluxes of the neutrons and the photons which directly leak out from the proton tube are large and the energy is high ;

当前用于推导中子数据的主要氘核反应所用光子束流未得到标记，并且往往仅测量中子和质子的截面比率，而截面比率并不能有效区分单π介子生成和双π介子生成。

Often , only ratios of proton-neutron cross sections have been measured with at times insufficient separation of single and double pion production channels .
