M. Zarcone et S. Nuzzo, POTENTIAL SCATTERING T-MATRIX IN A STRONG STATIC MAGNETIC-FIELD AND ACOLLINEAR LOW-FREQUENCY RADIATION-FIELD, Physical review. A, 52(3), 1995, pp. 2185-2194
Several approximations to the T matrix for collisions by a static shor
t-range potential in the presence of a strong static magnetic field an
d a collinear polarized radiation field are considered. We discuss the
ir different ranges of validity and compare the expressions of the T m
atrix in the different approximations.
