Theory for the Rydberg states of helium: Results for $2\le n\le 35$ and comparison with experiment for the singlet and triplet $P$-states

G. W. F. Drake, Aaron T. Bondy, Oliver P. Hallett +1

High precision variational calculations in Hylleraas coordinates are presented for all singlet and triplet $P$-states of helium up to principal quantum number $n=35$ with a unifo…
