   Partial Wave Unitarity ??
   
   Is there anyone who deals with "Partial Wave Unitarity" in Quantum Mechanics before??

   "Partial wave unitarity" means that the largest possible scattering amplitude squared (|A|^2) for any partial wave is when sin^2(delta)=1, where delta is the phase shift.
   This means that |A|^2 is limited by 4 pi(2L+1)^2/k^2.
   That is for spinless particles. Spin factors come in otherwise.
   Many people deal with this.
