Cobalt alloys have been used in nuclear reactor design because these alloys have favourable mechanical properties at high temperatures. In this work, the nuclear cross section data of ⁵⁹Co(n,2n)⁵⁸Co, ⁵⁹Co(n,3n)⁵⁷Co, ⁵⁹Co(n,4n)⁵⁶Co, ⁵⁹Co(n,np)⁵⁸Fe, ⁵⁹Co(n,t)⁵⁷Fe, ⁵⁹Co(n,³He)⁵⁷Mn and ⁵⁹Co(n,2nα)⁵⁴Mn reactions were obtained by using TALYS 1.8 and ALICE/ASH codes. Effects on the cross section data of nuclear level density models in the calculations were investigated. In addition, the obtained results of the cross section calculations are discussed and compared with the measured values from the literature.

The discrete level information deficiency requires usage of level density models in cross section calculations. The total reaction cross sections for gamma-induced reactions through the six level density models with a consistent parameterization of some lanthanides (^{141}Pr, ^{142}Nd, ^{144}Sm, ^{153}Eu, ^{159}Tb, ^{160}Gd, ^{165}Ho, ^{175}Lu) were calculated using TALYS 1.6 in the incident energy range from 5 to 30 MeV. All calculations from the present study were compared with each other and with data available in the literature.

The odd-odd nuclei are characterized by a level density which is high already in the low-energy region. This case displays a full complexity of the interwoven shell-model and collective degrees of freedom and thus provides an interesting testing ground for the pattern of nuclear level density. The level density of the odd-odd nucleus ¹⁹⁶Au is investigated in the interacting boson-fermion-fermion model which accounts for collectivity and complex interaction between quasiparticle and collective modes. In the present work, the IBFFM pattern of total and parametric dependent level densities is investigated and compared to the pattern found in previous investigations in the framework of combinatorial, thermodynamic and spectral distribution approaches.
