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.

Yes, there are many scientists who have studied and continue to study Partial Wave Unitarity in Quantum Mechanics. It is an important concept in understanding the behavior of particles at high energies and is used in various theoretical models and experiments. By considering the unitarity of partial waves, we can ensure that the total probability of all possible outcomes in a scattering process remains at 100%. This is crucial in maintaining the fundamental principles of quantum mechanics, such as conservation of energy and momentum. Researchers use Partial Wave Unitarity to analyze and interpret data from particle colliders and other high-energy experiments. So, to answer your question, yes, Partial Wave Unitarity is a well-studied and important concept in the field of Quantum Mechanics.
