19.7 The variation principle can be used to formulate the wavefunctions of electrons in atoms as well as molecules. Suppose that the function Wma = N(a)e* with N(a) the normalization constant and a an adjustable parameter, is used as a trial wavefunction for the 1s orbital of the hydrogen t atom. Show that 3ah? 2a - 2e E(a)=- where e is the fundamental charge, and µ is the reduced mass for the atom. What is the minimum energy associated with this trial wavefunction?
