%X Optical model is one of the models developed to explain nuclear reactions. It allows us to investigate the elastic scattering in the presence of absorption effects. The optical model is very important for nuclear reactions, since it defines how the cross sections of compound and the pre-equilibrium nuclear reactions separated to the opened reaction channels. Level density information along with the optical model potential perhaps the most important component for reliable theoretical analysis of the cross section, energy spectrum and other observable nuclear reaction values. In this study, cross section calculations have been done for 181Ta(¦Á,n)184Re, 181Ta(¦Á,2n)183Re, 181Ta(¦Á,3n)182Re ve 181Ta(¦Á,4n)181Re reactions by using different level densities and optical models. In the calculations Watanabe corrected Koning-Delaroche, McFadden- Satchler, Demetriou-Grama-Goriely and Avrigeanu models have been used for optical models while Constant Temperature Fermi Gas, Back-Shifted Fermi Gas and Generalised Superfluid models have been selected for level density models. All calculations have been performed with TALYS 1.8 code. Obtained results have been compared with the data taken from International Experimental Nuclear Reaction Data Center (EXFOR). Relative analysis of variance was used in the comparison of the calculations with the experimental data
