| Abstract: | The Feshbach-Rubinow approximation and its improved versions have been applied to the H2+ ion system.The ground-state energies are calculated with these different methods.The best ground-state energy obtained is only 2% higher than the experimental result.Given the simplicity of the method,this accuracy is quite remarkable.It is shown that the screening effect plays a less significant role and the effective potential between the two protons is probably of most importance in this problem. |
