The generalized potential energy function for diatomic molecules

New experimental data on the K2 state analyzed with the multi-parameter approach

“…where R is the interatomic distance, N is the leading power of the theoretically predicted inverse-power long-distance asymptotic behavior U MLJ (R) $ D e À C N /R N , and p is a Š urkus parameter (positive integer as a rule, see [42,43]). For the K 2 a 3 R þ u molecular state, which dissociates to the 4s + 4s atomic states, N = 6.…”

LEVEL: A computer program for solving the radial Schrödinger equation for bound and quasibound levels

“…that was introduced by Šurkus et al [26], and include the familiar Dunham [19], Simons-Parr-Finlan [28], and Ogilvie-Tipping [29] expansions as special cases that are invoked by particular choices for its parameters q, a S , and b S (see discussion of READ # 10 in Appendix B).…”

Analysis of the Na2 state above and below the 3s+3d atomic limit

“…where R is the interatomic distance, R e is the equilibrium interatomic distance, D e is the dissociation energy, T e " U MLJ (R e ) is the energy at the bottom of the well, N is the leading power of the theoretically predicted inverse-power long-range asymptotic behavior U MLJ (R) $ T e + D e À C N /R N , and p is a Š urkus parameter (positive integer as a rule, see [36,33]). We decided to apply the analogous approach to the current analysis of the Na 2 4 3 R þ g state.…”
