Theoretical and experimental determination of the lowest excited states of the Kr*2 excimer

Abstract
The potential energy curves of the Kr*2 excimer dissociating into Kr (4s24p6 1S0)+Kr*(4s24p55s) are determined (i) theoretically from ab initio CI calculation and semiempirical SO coupling and (ii) experimentally from the temperature dependence of absorption profiles. The results are carefully examined with the help of theoretical simulation of line profiles using semiclassical or quantal models.
