Abstract:
An efficient basis set for use with the Harris, Engerholm and Gwinn solution of one-dimensional vibrational potentials has been derived from centrosymmetric sturmian Laguerre functions using the l = 0 condition. Six-figure accuracy is achieved for n bound levels of the Morse and Fues potentials using 4n sturmian functions. With simple formulas and sparse arrays, convergence to all bound levels is achieved.
