In [[quantum mechanics]], '''Bargmann's limit''', named for [[Valentine Bargmann]], provides an [[upper bound]] on the number ''N''<sub>''l''</sub> of [[bound state]]s in a system. It takes the form
 
:<math>N_l \leq \frac{1}{2l+1} \frac{2m}{\hbar^2} \int_0^\infty r |V(r)|_{V<0}\, dr</math>
 
Note that the [[Dirac delta function]] [[potential]] attains this limit.

Greetings. Let me begin by telling you the author's name - Phebe. To gather coins is what his family members and him appreciate. For a while I've been in South Dakota and my mothers and fathers reside nearby. I used to be unemployed but now I am a librarian and the wage has been truly fulfilling.
