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..., , ## Theory for the Rydberg states of helium: Results for 2 ≤ n ≤ 35 and comparison with experiments for the singlet and triplet P states

##### Overview

For each *n = 2, 3, 4, ..., 35*, there is a text file in He_nPfinl.tar.gz entitled He_*n*Pfinl.txt 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. For example, He_2Pfinl.txt contains the matri..., ,
