Reaction rate constants have been calculated for electronic transitions in ##IMG## [http://ej.iop.org/images/0963-0252/29/2/025004/psstab5f42ieqn3.gif] {${\mathrm{Kr}}_{2}^{+}$} ions and for their decay as induced by collisions with krypton atoms and/or spontaneous radiation processes. The rate constants have then been used in a series of modelings of electronic relaxation in the ions in cold krypton plasmas with the main focus on relaxation times and final states. It has been shown that the collision-induced (non-radiative) relaxation is much faster than the radiative one and completely dominates with typical relaxation times ranging between nanoseconds and microseconds. The relaxation always ends up in the ##IMG## [http://ej.iop.org/images/0963-0252/29/2/025004/psstab5f42ieqn4.gif] {${\mathrm{Kr}}_{2}^{+}$} electronic ground state, high electronic excitations survive for longer times than lower excitations due to spin–orbit coupling ...
