Lorentz It is believed that when the radiation oscillator is impacted, the vibration will be interrupted suddenly. The emission is interrupted during the collision, and the radiation re emitted after the collision is independent of the radiation phase before the collision. Therefore, the harmonic oscillator with angular frequency emits waves of finite length, whose length is determined by the interval between two collisions. Considering the distribution probability of radiation wave according to the time length, the distribution of (ω) is the collision damping constant. Considering the near radiation of perturbed particles before and after collision atom The more general distribution form of radiation intensity can be obtained by changing the phase of radiation wave. This means that in addition to the spectral line broadening, there is also the displacement β of the spectral line center (the maximum value is not at the line center=).
