Description

The interaction between an F center and neutral hydrogen atoms, the most simple paramagnetic defects in ionic crystals, is described in terms of a perturbation theory of two square potential wells. The good agreement with experimental data indicates that lattice distortion due to the presence of the hydrogen atoms is negligible

Abstract (Portuguese)

Descreve-se a interacao entre um centro F e atomos neutros de hidrogenio, os defeitos paramagneticos mais simples em cristais ionicos, em termos de uma teoria de perturbacoes de dois pocos quadrados. O bom acordo com os dados experimentais indica que a distorcao da rede, devida a presenca dos atomos de hidrogenio e desprezivel
