R-matrix and MQDT investigation of low-lying Rydberg states of the HeH

We report R-matrix calculations of low-lying Rydberg states of the hydrohelium molecular ion HeH+ corresponding to 1Δ and 3Δ symmetry. The calculations include states with principal quantum numbers 3 ≤ n ≤ 10. For n = 3 and n = 4 the present results are compared with those of Green et al. [1,2] and Loreau et al. [3]
