The H molecular ion: a solution
Combining the WKB expansion at large distances and Perturbation Theory at
small distances it is constructed a compact uniform approximation for
eigenfunctions. For lowest states 1s\si_{g} and 2p\si_{u} this
approximation provides the relative accuracy (5 s.d.) for
any real in eigenfunctions and for total energy it gives 10-11 s.d.
for internuclear distances . Corrections to proposed
approximations are evaluated. Separation constants and the oscillator strength
for the transition 1s\si_{g} \rar 2p\si_{u} are calculated and compared with
existing data.Comment: 16 pages, 4 figures, 6 tables, typos are corrected and small
