Popis:	A collisional radiative model for Kr III in the ultraviolet regime is developed. For this purpose, atomic parameters for 4s24p4, 4s4p5, 4s24p3nl, and 4s24p35d configurations with n ranging from 5 to 7 and l=s,p, using the multiconfiguration Dirac–Hatree–Fock method are calculated. The effects of Breit and radiative quantum electrodynamic corrections are also included. Electron impact excitation cross-sections from the ground state, along with four metastable states arising from the 4s24p4 configuration to all fine structure levels of interest, are calculated using the relativistic distorted wave method. The reliability of the model is tested by comparing the predicted results with the previous measurements.
