The true diatomic potential as a perturbed Morse function

Journal of Computational Chemistry, 1995
AbstractThe problem of representing a diatomic (true) Rydberg‐Klein‐Rees potential Ut by an analytical function Ua is discussed. The perturbed Morse function is in the form Ua = UM + ∑bnyn, where the Morse potential is UM = Dy2, y = 1 −exp(−;a(r − re)). The problem is reduced to determination of the coefficients bn so Ua(r) = Ut(r).

Modified Morse potential for unification of the pair interactions

The Journal of Chemical Physics, 2007
We designed a novel model potential that unifies the pair interactions including the well known Morse and Lennard-Jones potentials. Using two parameters, the interactions at the minimum, short range, and long range of the new model potential can be controlled separately, so the potential is very flexible to fit various systems.

AN ALGEBRAIC APPROACH TO THE q-DEFORMED MORSE POTENTIAL

Modern Physics Letters A, 2009
We have obtained the creation and annihilation operators directly from the eigenfunction for the general deformed morse potential in one-dimensional Klein–Gordon equation with equally mixed vector and scalar potentials and also in the Schrödinger equation, we show that these operators satisfy the commutation relation of the SU(1, 1) group. Then we have

Group theory of the Morse potential

1980
We map the problem of a Morse potential in one dimension into a two-dimensional harmonic oscillator. The symmetry group for this problem is U(2). Starting from the dynamical group Sp(4), we use two different chains of groups including SU(1,1) and U(2) respectively.

JWKB quantization of the Morse potential

Physics Letters A, 1992
Abstract We consider an improved JWKB approximation which takes into account phase distortions of JWKB functions that are caused by boundary conditions at r =0 for the S wave solution of the Schrodinger equation for potentials nonsingular at r =0.

Exploring the Morse Potential: MorsePotential.mcd

Journal of Chemical Education, 1998
The goal of the 'Exploring the Morse Potential' document is to provide hands on practice with the Morse potential energy function and the units used for calculating this potential. In the document is a step-by-step description of how to create the Morse potential function for HCl.

Algebra representations on eigenfunctions of the Rosen–Morse potential

Journal of Mathematical Physics, 1987
The bound state eigenfunctions of the Rosen–Morse [N. Rosen and P. M. Morse, Phys. Rev. 42, 210 (1932)] potential are investigated using ladder operators that give a representation of the algebra A1. The representations are generally infinite-dimensional and indecomposable, the representation space containing unbounded functions as well as the ...
