✦ Synopsis

It is shown that the RITZ variation method can be interpreted as a method of calculating the eigenfunctions of the operator% where 9 is the projection operator projecting the function space spanned by a complete set of basis functions into the subspace given by the functions chosen for the linear combina-tion_ F,rom this one can cieduce the 6 2-criterion for the wave functions. Furthermore. the cnecm-62 and 6-(f) variation methods are tested on the H-atom.
