Two free electrons approach each other, so they start to emit photons due to bremsstrahlung. Where does the angular momentum carried away by the emitted photons come from?

Angular momentum during bremsstrahlung

In summary, angular momentum during bremsstrahlung is a measure of the rotation or spin of a particle as it emits radiation. It plays a crucial role in determining the direction and energy of the emitted radiation, and is conserved during bremsstrahlung, with the emitted photon carrying away the change in the particle's angular momentum. The energy of the emitted photon is directly related to the change in angular momentum, and angular momentum is also important in other physical processes such as collisions, nuclear decay, and electromagnetic interactions.

I'm sure experts will jump on the phrasing 'start to emit photons' . Never mind. I suppose you googled ? I got lots of useful links.
Angular momentum is conserved; the electron loses what the photon carries off (ahem...). The presence of another charged particle (normally a nucleus) that interacts through a virtual photon is essential ! There is no Feynman diagram for electron in, photon + electron out !

1. What is angular momentum during bremsstrahlung?
Angular momentum during bremsstrahlung is the measure of the rotation or spin of a particle as it emits radiation, known as bremsstrahlung radiation. It is a conserved quantity in all interactions, including bremsstrahlung, and can be calculated by multiplying the mass of the particle by its velocity and the distance from the axis of rotation.
2. How does angular momentum affect bremsstrahlung radiation?
Angular momentum plays a crucial role in bremsstrahlung radiation as it determines the direction and energy of the emitted radiation. The change in the particle's angular momentum during bremsstrahlung is equal to the angular momentum of the emitted photon, which is responsible for the energy loss of the particle.
3. Can angular momentum be conserved during bremsstrahlung?
Yes, angular momentum is a conserved quantity during bremsstrahlung. This means that the total angular momentum of the particle before and after it emits radiation remains constant. The emitted photon carries away the change in the particle's angular momentum, ensuring the conservation of this quantity.
4. How does the energy of the emitted photon relate to angular momentum during bremsstrahlung?
The energy of the emitted photon is directly related to the change in the particle's angular momentum during bremsstrahlung. The greater the change in angular momentum, the higher the energy of the emitted photon. This is because the energy of the photon is equal to the product of Planck's constant and the change in angular momentum.
5. Is angular momentum important in other physical processes besides bremsstrahlung?
Yes, angular momentum is a fundamental quantity in many physical processes, including bremsstrahlung. It is a conserved quantity in all interactions, including collisions, nuclear decay, and electromagnetic interactions. Understanding and calculating angular momentum is essential in studying and predicting the behavior of particles and systems.
