Abstract
The present paper developed two kinds of new time-dependent methods in quantum scattering calculation. One method is to combine a split-oper ator method with a differential method to achieve better convergent pr operty than a pure differential method and better adaptive property in a multidimensional case than the pure split-operator method. Another method is to adopt a desired time-dependent variational principle to a chieve variational correction in numerical calculations, which can imp rove the result from direct numerical evaluation with little additiona l consumed time.
