An extensive calculation for electron impact excitation cross-sections of Kr⁺ ion is performed using relativistic distorted wave theory. The transitions considered are from the ground state i.e. 4s²4p⁵ (J=3/2) to the 4s²4p⁵ (J = 1/2), 4s4p⁶ (J=1/2) levels and fine structure levels of 4s²4p⁴5s, 4s²4p⁴5p, 4s²4p⁴6s, 4s²4p⁴6p, 4s²4p⁴4d and 4s²4p⁴5d excited states. The transition matrix is evaluated using the relativistic multi-configuration Dirac-Fock bound state wave functions of the initial and final states of Kr⁺ ion obtained from the GRASP2K program. The 4s²4p⁵, 4s4p⁶, 4s²4p⁴5s, 4s²4p⁴5p, 4s²4p⁴6s, 4s²4p⁴6p, 4s²4p⁴4d and 4s²4p⁴5d configuration state functions are used to calculate the required wave functions. The incident and scattered projectile electron continuum wave functions are calculated numerically by solving the Dirac equations using static potential of the target ion. Oscillator strengths and transition probabilities are calculated and reported for the dipole allowed transitions, making these available to check the accuracy of the bound state wave functions for future comparison purposes. The detailed excitation cross-sections and their corresponding excitation rate coefficients are reported for considered 116 fine-structure excitation transitions from the ground state 4s²4p⁵ (J=3/2). Further, analytic fittings of the obtained cross-sections with respect to incident electron energy are also performed for all the transitions considered in the present work so that these can be directly used in any plasma model for diagnostics purposes. In addition, using the obtained magnetic sub-level cross-sections, the degree of linear polarization of the photon emissions from the decay of electron impact excited anisotropic states of Kr⁺ ion through the dipole allowed transitions is calculated and reported.
