Hermite Gaussian functions modulated by plane waves: a general basis set for bound and continuum states

  • Published:
Il Nuovo Cimento D

Summary

Characteristics and advantages of a basis set of Hermite Gaussian functions modulated by plane waves (THGF) are discussed and analysed in a specific case. The expressions of the prototype integrals necessary in variational calculations for bound and continuum states are given.

Riassunto

Si discutono caratteristiche e vantaggi di funzioni gaussiane moltiplicate da polinomi di Hermite di ogni grado e modulate da onde piane, quali funzioni di base per l'espansione di orbitali atomici e molecolari. I vantaggi di tali funzioni di base sono illustrati in un caso specifico. Si danno le espressioni degli integrali prototipo coinvolgenti tali funzioni e necessari nei calcoli variazionali per stati legati e del continuo.

Резюме

Обсуждаются и анализируются в специальном случае характеристики и преимущества базисной системы функций Гаусса, умноженных на полиномы Эрмита и модулированных плоскими волнами. Приводятся выражения для прототипов интегралов, которые необсходимы при вариационных вычислениях для связанных и непрерывных состояний.
