Which mechanism causes spectral line broadening in plasmas?

💡 Explanation

The Stark effect broadens spectral lines because the fluctuating electric fields from nearby ions cause energy level splitting via Quantum Mechanical Coupling with free neighbours; therefore, spectral lines broaden, rather than exhibiting Doppler shift due electron thermal motion or bremsstrahlung due to electron-ion. interactions.
