Abstract

Using the BetheSalpeter equation as a starting point it is shown that the normal peripheral model with absorption corrections for quasitwoparticle scattering can be derived with plausible highenergy approximations It is then shown that essentially the same approximations applied to the BetheSalpeter equation for singleparticleproduction reactions yield a formula for correcting the double peripheral model for absorption These absorption formulae are then written in the overlap integral form which is suitable for numerical evaluationИспользуя уравнение БетеСалпетера как исходный момент показывается что нормальная периферическая модель с абсорбционными поправками для квазидвухчастичного рассеяния может быть выведена с помощью правдоподобных приближений высокой энергии Затем показывается что существенно те же приближения примененные к уравнению БетеСалпетера для реакций рождения одной частицы приводят к формуле исправляющей двойную периферическую модель для поглощения Затем выписываются эти абсорбционные формулы в перекрывающейся интегральнои форме которая удобна для численных расчетовPartendo dall’equazione di Bethe e Salpeter si dimostra che il modello periferico normale con le correzioni di assorbimento per lo scattering di due quasi particelle può essere derivato con plausibili approssimazioni in alta energia Si dimostra allora che essenzialmente le stesse approssimazioni applicate all’equazione di Bethe e Salpeter per le reazioni cou produzione di una sola particella forniscono una formula per la correzione dell’assorbimento del modello periferico doppio Si serivono queste formule di assorbimento nella forma dell’integrale di sovrapposizione adatta per i calcoli numerici
