Data tables of matrix elements used to calculate the ionization energies of the Rydberg P-states of helium for principal quantum number 2 ≤ n ≤ 35

The archive contains data tables used to calculate the nonrelativistic,
relativistic and quantum electrodynamic energies of the P-states of helium
up to n = 35. For each n, there is a text file entitled He_nPfinl.txt
located in He_nPfinl.tar.gz that contains a summary of all matrix elements
used in the calculations for both singlet and triplet states, together
with convergence tables and uncertainty estimates. At the end of each text
file, there is a summary table containing calculated ionization energies
of the respective atomic states that can be compared directly with
experimental measurements, in analogy with Table IV and the 11 comparisons
with experiment contained in the parent article
https://link.aps.org/doi/10.1103/1dbh-rjjn. The additional tables of
matrix elements may be useful to others wishing to replicate the present
results, or search for systematic trends. The matrix elements were
calculated with respect to two-electron wave functions obtained from
variational solutions to the quantum mechanical three-body problem in
fully correlated Hylleraas coordinates, and using extended precision
arithmetic.
