Angular-momentum reduction of the faddeev equations
Tóm tắt
Angular-momentum reduction of the Faddeev equations is re-examined. The symmetrical and unsymmetrical coupling schemes are directly related. A simpler explicit form is proposed, from which it appears that the number of coupled amplitudes has been overestimated. A sign oversight, relevant for calculating states with nonzero orbital momentum, is pointed out in some previous treatments.
