Summary
For a system having a finite number of channels the bound states of the free and complete Hamiltonian are shown to be simply related to the determinant and trace of theS-matrix.
Riassunto
Si dimostra che, per un sistema con un numero finito di canali, gli stati legati dell’hamiltoniano libero e completo sono connessi in maniera semplice al determinante ed alla traccia della matriceS.
