Abstract：
In the deeply inelastic e-A scattering, the gluon radiation induced by multiple scattering will lead to medium modification of the parton fragmentation functions and also associate with the energy loss of the leading quark. To obtain the hard partonic part of quark-gluon double scattering, one can do a complete calculation within the framework of generalized factorization in perturbative QCD. In another way one can utilize the approach of helicity amplitude approximation(HAA) to calculate the amplitude of gluon radiation. However, the two methods are both complicated and tedious. In this paper, we will introduce a new approach which enables one to calculate easily the amplitude for gluon radiation in multiple scattering. The final results obtained by using our new approach agree exactly with the complete calculation in perturbative QCD.
