Spectra and oscillator strengths of 3p⁶3d⁹--3p⁵3d¹⁰ and 3p⁶3d⁹--3p⁶3d⁸4p transitions for cobalt-like Sn²³⁺ ion

This paper calculates the spectra and oscillator strengths for highly ionized cobalt-like Sn²³⁺ ions 3p⁶3d⁹--3p⁵3d¹⁰, 3p⁶3d⁹--3p⁶3d⁸4p transitions by using a multi-configuration self-consistent field method program together with the proposed fitting formula. The calculations have a good agreement with observations.
