Abstract
TOR momentum operators by applying projection operators and we form an orthogonal set. For the uniform solution, St=i+ (LkAtg kt+CC). k0 Noting that the method has a variational aspect, L need not be taken from the small-oscillation analysis but may be freely chosen to describe average largeamplitude effects. We obtain improved ground-state energy and single-and multiple-excitation spectra.
