A Gaussian profile is achieved due to thermal motion of particles in an effect referred to as this scientist's namesake broadening of spectral lines.
This scientist names a limit that can be exceeded using the resolved sideband method; that limit, which is equal to h-bar times the inverse of the excited state lifetime over 2 times Boltzmann's constant, is less strict than the recoil limit. A Gaussian profile is achieved due to thermal motion of particles in an effect referred to as this scientist's namesake broadening of spectral lines. Atoms are held in a magneto-optical trap and made to absorb and re-emit (*) photons in a form of laser cooling named for him. The frequency change caused by this scientist's namesake effect is given by the ratio of the sum of source velocity and wave velocity to the sum of receiver velocity and wave velocity. For 10 points, name this scientist who predicted "red" and "blue" wavelength shifts caused by a moving wave source.
