With the continuous improvement of computer performance,computational physics develops rapidly,and its proportion in modern physics is increasing.It has great significance to study the teaching of computational physics.in order to developing the research and innovation ability of students,we explored the teaching of computational physics course from the teaching goal of computational physics course to the specific links of curriculum design and implementation,and carried out the teaching practice with examples,the effect is better.It has important reference value for the teaching of computational physics in the future.While conducting teaching and research,we used the method of computational physics to simulate the nuclear reaction process and calculate the nuclear reaction data.Such data are indispensable in the utilization of nuclear energy.As the exposure of the energy crisis,the role of nuclear energy as a clean and efficient energy is becoming more and more remarkable.By increasing and transmuting radioactive waste and making nuclear energy utilization more economical and secure.the Accelerator Driven Sub-critical System?ADS?and the Thorium Molten Salt Reactor Nuclear Energy System play an important role in improving the utilization of nuclear fuel.It need a large number of the full set of accurate nuclear reaction micro data induced by proton and neutron in the design and manufacture of the two system,such as the microscopic data of n+^74,75,77,79As,n+^{127,130,131,135}I and n+¹⁶⁵Ho,because the lack of the neutron nuclear reaction experimental data for natural As and Ho,therefore,it is necessary to calculate and analysis the full set of microcosmic data for n+^74,75,77,79As,^{127,130,131,135}I and ¹⁶⁵Ho nuclear reaction theoretically.Based on the experimental data of natural As and Ho,using the optical model theory,the optimal optical potential parameters for ^74,75,77,79As,^{127,130,131,135}I and ¹⁶⁵Ho are obtained.On the premise of the parameters,The cross sections,energy spectra and double differential cross sections for n+^74,75,77,79As,^{127,130,131,135}I,¹⁶⁵Ho reaction in 0.1-20 MeV are calculated and analyzed by the UNF program which based on the optical model.the distorted wave Bom approximation theory,the unified Hauser-Feshbach theory and exciton model.By comparing and analysing with experimental data,we think the calculation results are basically reasonable.The data obtained in this work will play an important role in the application of nuclear engineering and the research of nuclear reaction.
