Summary
We present a detailed diseussion of the interpretation of a seattering process within the framework of relativistic quantum mechanics. This argument is particularly well suited to the seattering of charged scalar particles in an external electromagnetic field, but it breaks down for spin-1/2 particles. In the latter case, we can improve certain features if we use the Klein-Gordon equation instead of the Dirae equation.
Riassunto
Sipresenta una discussione dettagliata dell'interpretazione di un processo di scattering nel contesto della meccanica quantistica relativistica. La discussione si adatta particolarmente allo scattering di particelle scalari cariche in un campo elettromagnetico esterno, ma non vale per le particelle di spin 1/2. In quest'ultimo caso, si possono perfezionare alcune caratteristiche usando l'equazione di Klein-Gordon invece di quella di Dirac.
Резюме
Мы предлагаем подробное обсуждение интерпретации процесса рассеяния в рамках релятивистской квантовой механики. Частично эта аргументация хорошо подходит для рассеяния заряженных скалярных частиц во внешнем электро-магнитном поле, но не применима для частиц со спином 1/2. В последнем случае мы можем уточнить некоторые детали, если мы используем уравнение Клейна-Гордона вместо уравнения Дирака.
