Azot Atomunda İki Foton Soğurma Tesir Kesitlerinin Hesaplanması

Abstract

Bu çalışmada azot atomunda bazı ince yapı seviyeleri arasındaki geçişler için iki foton soğurma tesir kesitleri hesaplanmıştır. İki foton soğurma tesir kesiti ifadesi açısal katsayılara ve radyal geçiş integrallerine bağlı olarak verilir. Açısal katsayıların hesaplanmasında Racah yöntemi, radyal geçiş integrallerinin belirlenmesinde ise en zayıf bağlı elektron potansiyel model teorisi kullanılmıştır. Elde edilen sonuçların literatürle uyumlu olduğu görülmüştür.

Keywords

The Calculation of Two-Photon Absorption Cross-Sections in Nitrogen Atom

Abstract

In this study, two-photon absorption cross-sections for transitions between some fine structure levels in nitrogen atom have been calculated. The expression for the two-photon absorption cross-section is given to be depend on the angular coefficients and radial transition integrals. The Racah method was employed in calculation of the angular coefficients and the weakest bound electron potential model theory was used to compute the radial transition integrals. It has been found that the results obtained are in good agreement with the literature.

Keywords

• Nitrogen Atom, two-photon absorption cross-section, the weakest bound electron potential model theory
