Bargmann's limit
text:
In quantum mechanics, Bargmann's limit, named for Valentine Bargmann, provides an upper bound on the number N ℓ of bound states with azimuthal quantum number ℓ in a system with central potential V . It takes the form This limit is the best possible upper bound in such a way that for a given ℓ , one can always construct a potential V ℓ for which N ℓ is arbitrarily close to this upper bound. Note that the Dirac delta function potential attains this limit. After the first proof of this inequality b
