Abstract: | The equilibrium geometries, nuclear distances, wave functions and energies for the XY 2+ , X2Y+, Y2H+ (X=Li, Na, K; Y=Rb, Cs), resp. the X2H+, X2Y+ (X, Y=Cu, Ag, Au) triatomic alkali ions, resp. noble metal ions, further the dissociation energies for the X2Y+→X++XY; XY 2+ →Y++XY and Y2H+→Y++YH processes are determined with the pseudopotential method. The calculations were performed using the Hellmann-type analytical potential with simple floating-type one-centre wave function. |
