The Compton effect with no scattering angle, also known as the zero angle Compton effect, is a phenomenon in which a photon loses energy when it collides with a stationary electron. Unlike in the traditional Compton effect, the scattered photon does not change direction and there is no deflection angle.
In the traditional Compton effect, the scattered photon changes direction and has a deflection angle. This is due to the transfer of energy and momentum between the photon and the electron. In the Compton effect with no scattering angle, the electron is stationary and there is no change in the direction of the scattered photon.
The Compton effect with no scattering angle occurs when a photon collides with a stationary electron. The energy of the photon is partially transferred to the electron, causing the photon to lose energy and decrease in wavelength. This is due to the conservation of energy and momentum in the collision.
The energy of the scattered photon in the Compton effect with no scattering angle can be calculated using the formula E' = E/(1 + mc^2/E), where E is the initial energy of the photon, m is the mass of the electron, and c is the speed of light.
The Compton effect with no scattering angle is an important phenomenon in understanding the behavior of photons and electrons in collisions. It also provides evidence for the wave-particle duality of light, as the scattered photon behaves like a particle with a decreased energy and wavelength. This effect is also used in various applications, such as in medical imaging techniques like Compton scattering tomography.
