Summary: | 碩士 === 國立中央大學 === 物理研究所 === 82 === A approach for sloving the time-dependent wave function in
quantum scattering problem is done in the interaction picture.
The conventional wave packet method ,which directlt sloves the
time-dependent Schrodinger equation ,normally requires a large
number of grid points since the Schrodinger picture wave
function both travels and spreads in time. There are two for
using interactiion picture wave function. The first,a
numerical gridn is required due to the localized nature of
picture wave function,since it's not a traveling wave and doesn'
t in coordinate space.The second,the interaction picture wave
slowly with time and is essentially independent ofng the use of
a large time in the numerical integrate the time dependent and
obtain S matrix and K matrix (tangent of phase shift) for s d
wave.
