In this study, neutron-emission spectra produced by (alpha,xn) reactions for some structural fusion materials such as Al-27, Cr-53, Fe-56 and Ni-58,Ni-60,Ni-62 have been investigated. Hybrid model, geometry dependent hybrid model and full exciton model have been used to calculate the pre-equilibrium neutron-emission spectra. For the reaction equilibrium component, Weisskopf-Ewing model calculations have been preferred. The mean free path parameter's effect for (alpha,xn) neutron-emission spectra has been examined. The obtained results have been discussed and compared with the available experimental data and found agreement with each other.
