Abstract
The variational principle is used to obtain solutions to Schrodinger's equation for a particle in the Yukawa potential. A Laguerre basis set extended by an extra function is employed in the calculations. A spec ial parameter used in the extra function and its relation with the sys tems energy results in utilizing an auto-coherent scheme. Considerable improvement seems to be achieved especially in the critical region wh ere the screening parameter approaches its threshold value.
