“Structure of Spectral Lines” [PDF]
Nature, 1947 In Nature of August 23, p. 244, Dr. D. A. Jackson reviews my recent book on “High-Resolution Spectroscopy” (Methuen, 1947). After considerable hesitation and with much reluctance, I feel compelled to comment on several misrepresentations made by Dr. Jackson.

Intensity and Polarization of Radiation Emerging from Rotating Accretion Disc with Increasing Height
Universe, 2020 We consider the radiation emission in continuum and spectral lines from rotating accretion disc with the progressive increasing height. It is known that for the plane accretion disc with homogeneous atmosphere the wave electric field E is perpendicular ...

Stark Broadening of N VI Spectral Lines
Universe, 2023 Stark broadening parameters, line widths and shifts, for 15 N VI multiplets are calculated using semiclassical perturbation theory for temperatures from 50,000 K to 2,000,000 K, and perturber density of 1016 cm−3. As perturbers have been taken electrons,
