The theoretical visible transitions and spectra of W13+ ion from the Electron Beam Ion Trap are investigated by constructing and solving a collisional-radiative model (CRM) within the Quasi-Steady-State approximation. The necessary atomic data for constructing the CRM have been calculated using the relativistic configuration interaction (RCI) method and distorted wave approximation. The present results are in reasonable agreement with the available experimental observations and theoretical calculations. The relative intensities of the M1 transitions between the ground and low-lying excited fine-structure levels have been found to strongly depend on the electron density from n e =109 cm−3 to n e =1012 cm−3, which might be useful for the future diagnosis of the electron density of the plasma. • The experimental visible spectrum of W13+ ion was analyzed by the collisional radiative modeling with accurate atomic data. • The M1 transition between the ground and excited configuration of W13+ ions were assigned to the experimental spectrum. • The dependence of the spectrum intensity on the electron density was explained.
