Spin corrections to eikonal approximation

Спиновые поправки в зйконалыюм приближении

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

In the framework of the eikonal approximation we compute the spin corrections to the bound states of a spin-1/2 particle in a Coulomb potential. We first consider the case of scattering in a Yukawa potentialV(r)=−(exp[−μr])/r in the limit whereμ → 0. In the second part we give the correct treatment of the Coulomb potential, using off-shell eikonal scattering amplitudes.

Riassunto

Si calcolano, nell’approssimazione eiconale, le correzioni dello spin agli stati legati di una particella con spin 1/2 in un potenziale di Coulomb. Prima si esamina il caso dello scattering in un potenziale di YukawaV(r)=−Zα(exp [−μr])/r nel limite in cuiμ → 0. Nella seconda parte si tratta in maniera corretta il potenziale di Coulomb, con ampiezze di scattering eiconali esterne agli strati.

Реэюме

В рамках зйконального приближения мы вычисляем спиновые поправки к свяэанным состояниям частицы со спином половина в кулоновском потенциале. Сначала мы рассматриваем случай рассеяния на потенциале ЮкавыV(r)=−(exp [−gm r])/r в пределеμ → 0. Во второй части мы рассматриваем кулоновский потенциал, испольэуя зйкональные амплитуды рассеяния вне массовой поверхности.

  8. See,e.g., ref. (6). In that paper the authors argue that the computation of (2.6) can also be made in the forward direction. However, in this case the development (2.7) is no longer justified. Studying (2.6), withq=0, we found that it still possesses simple poles located atv=N. It also possesses poles of greater order (going to infinity). Moreover, the residues of the simple poles cannot be obtained in closed form.
