An inverse-scattering approach to the physics of transition metals

  • Published:
Il Nuovo Cimento D

Summary

A method is developed for the deduction of a transition metal ion potential from a knowledge of the phase-shiftηl (k). The method used is based on the distorted plane-wave scattering approximation for the deduction of nonsingular potentials from scattering phase shifts in an inverse-scattering approach. The resulting electron-ion potential obtained is a finite Dirichlet series sum of short-range exponential functions. The Fourier transform of the potential is obtained for applications in the area of transition metal solid-state physics.

Riassunto

Si sviluppa un metodo per la deduzione di un potenziale di ione metallico di transizione dalla conoscenza dello spostamento di faseηl (k). Il metodo usato è basato sull'approssimazione distorta dello scattering di onda piana per la deduzione di potenziali non singolari per spostamenti di fase di scattering in un approccio di scattering inverso. Il potenziale elettrone-ione risultante ottenuto è una somma di serie di Dirichlet finita di funzioni esponenziali a corto raggio. La trasformazione di Fourier del potenziale è ottenuta dalle applicazioni nell'area della fisica dello stato solido dei metalli di transizione.

Резюме

Развивается метод для определения ионного потенциала переходного металла с использованием фазового сдвигаηl (k). Предложенный метод предполагает использование искаженных плоских волн в процессе рассеяния для получения несинтуляторных потенциалов из фазовых сдвигов рассеяния в подходе обратного рассеяния. Полученный электрон-ионный потенциал представляет конечную сумму ряда Дирихле коротко-действующих экспоненциальных функций. Получается фурье-преобразование потенциала для использования в физике твердого тела переходных металлоб.
