Stark FWHM for the He I 5016 Å line as a function of the electron density. A large number of measured and calculated data are included. In this paper the line broadening for the (21 S-31 P) transition is calculated by using binary approximation (– – –) and including dynamical screening effect (–––). They are compared with the data of Gigosos et al. for pink circle (∘) independent and turquoise circle (∘) interacting particles [18, 19], (×) Bassalo et al. [41], (⋄) Berg et al. [42], orange circle (•) Pérez et al. [27], (▿) Chiang et al. [43], (▵) Diatta [44], (*) Milosavljević and Djeniže [45], (⊲) Kelleher [46], (□) Mijatović et al. [47], (⚪) Soltwisch and Kusch [40], and (+) Griem [1].
