Abstract
The convergence of single-channel scattering phaseshifts determined from the consistent variational method is examined. It is shown that if certain conditions are satisfied, then the variationally determined phaseshift will approach the true phaseshift monotonically from below. The possibility of pseudo-resonances or anti-resonances is discussed and illustrative calculations are presented.Keywords
