摘要: A variational trial wave function of the form ψ=f(r1)f(r2)g(r12) has been applied to ground state He I. In Sec. I, f(r) is taken be an arbitrary and g(r12) as linear. The slope are chosen yield minimum energy. energy, —5.79613RHehc, f compared with results earlier work obtained analytic functions. table charge distribution given. that from a Hartree‐Fock difference discussed.In II, exponential function. coefficient in exponent —5.78252RHehc, behavior g shown by its asymptotic series. probable effectiveness ψ if both ...
