| Abstract: | In the present paper,the Hamiltonion matrix elements of irreducible representations of the double group C_4 for d_5 configuration and the point-charge model are adopted to calculate the optical absorptionspectra of SiO_3:Mn~(2+).The calculatel results agree well with experimental spectra data.The results showoptical absorption spectra of SiO_3:Mn~(2+) is caused by the tetragonal distortion crystal field and Ma~(2+) isof highly ionic nature. |
