摘要: The general formula for the angular distribution in collisions between pairs of particles is simplified by performing explicitly all sums over magnetic quantum numbers. resulting expressions involve coefficients introduced Racah study complex atomic spectra. cross sections are expressed as series Legendre polynomials, each coefficient being manifestly real.The theory then specialized case nuclear reactions and scattering associated with one isolated resonance level compound nucleus. Formulas derived various differential reaction without change channel spin. interference terms potential written explicitly, both neutral charged particles.
