چکیده
|
A new application of variational monte carlo method is presented to study the helium atom under the compression effect of a spherical box with radius (rc). the ground-state energies of the helium atom were calculated for different values of rc. our calculations were extended to include li^+ and be^2+ ions. the calculations were based on the use of a compact accurate trial wave function with five variational parameters. to optimize variational parameters, we used the steepest descent method. the obtained results are in good agreement with previous results.
