# Accurate 2d finite element calculations for hydrogen in magnetic fields of arbitrary strength

## Description

Abstract Recent observations of hundreds of hydrogen-rich magnetic white dwarf stars with magnetic fields up to 10^5T (10^3MG) have called for more comprehensive and accurate databases for wavelengths and oscillator strengths of the H atom in strong magnetic fields for all states evolving from the field-free levels with principal quantum numbers n≤10. We present a code to calculate the energy eigenvalues and wave functions of such states which is capable of covering the entire regime of field stre... Title of program: H2db Catalogue Id: AERB_v1_0 Nature of problem The hydrogen problem in the presence of a magnetic field of arbitrary strength shall be solved for all states up to a principal quantum number of n = 10. We obtain the full energy vs. field strength function within a certain precision.
