Carl Ramsauer

Carl Ramsauer refers to the Ramsauer effect, which is a phenomenon in quantum mechanics observed in the scattering of electrons by atoms. More specifically, it describes the unexpected enhancement of the scattering cross-section of low-energy electrons as they pass through a target gas at low pressures. This effect was first observed by the German physicist Carl Ramsauer in the early 20th century. The phenomenon is significant for understanding electron-atom interactions and has implications for fields such as atomic physics and materials science.
