Summary
The sufficiency condition for the existence of solutions of the unitarity integral for the phase of the amplitude is discussed for the screened Coulomb scattering amplitudes.
Riassunto
Si discute la condizione sufficiente per l’esistenza di soluzioni dell’integrale di unitarietà per la fase dell’ampiezza nel caso di ampiezze di scattering schermato di Coulomb.
Реэюме
Для амплитуд рассеяния на зкранированном кулоновском потенциале обсуждается достаточное условие для сушествования рещений для интеграла унитарности для фаэы амплитуды.
