We have applied the fast-Fourier-transform (FFT) method for propagating the solution of the timedepcndent Schriidinger equation for a reactive atom-diatom collision in hyperspkrical coordinates. Iithe present paper the dimensionaliv of the quantum subspace is reduced to two by introducing a semiclas
