Coupled channel method

WebAs a whole, there are two methods to perform such coupled channel optical model calculations from the physics and mathematics point of view, one is the conventional matrix method called standard coupled channel (SCC) method, the other is ECIS (sequential iteration of coupled equations) method'2' which provides an alternative to the former. … WebThe idea is to couple the spin of one of the interacting atoms to the two-body relative motion. In this way, a noticeable displacement can be induced on the wave function of the relative motion under the action of a microwave spin-flip transition.
