If I have an electron and positron in a vacuum, initially at rest with respect to each other and in close proximity, will they produce any bremsstrahlung radiation?
Within the problems to define the emission time: Simultaneously. It doesn't make sense to pair them either. They have four different energy values.metastable said:are the 4 photons emitted sequentially in pairs or simultaneously?
metastable said:will I ever measure the subsequent e- + e+ -> γ + γ radiation emitted totaling less than 2 *
0.5109989461(13) MeV (electron rest mass)?
Yes, that's what the article told you already.metastable said:Does the positronium system have less mass/energy than its constituent fundamental particles?
A well-defined distance doesn't correspond to a well-defined energy and small distances cannot be treated classically, as everyone in the thread told you already.metastable said:Can I write an equation relating the electron mass with its antiparticle charge-separation distance?

You can measure their arrival time.metastable said:how am I to reasonably conclude they were emitted simultaneously?
"Emission duration" is not a meaningful concept.metastable said:Is the emission duration for each photon independent of the 4 different wavelengths?
metastable said:how do I reasonably conclude I haven't just calculated the varying emission durations
mfb said:"Emission duration" is not a meaningful concept.
Vanadium 50 said:Again, where are you going with this? If you have some bigger picture in mind, why won't you tell us what it is? Or are you just flinging random questions at us?

Electron-positron bremsstrahlung is a type of electromagnetic radiation that is produced when an electron and a positron (the antiparticle of an electron) interact and change direction due to their electric fields.
Unlike other types of radiation, such as X-rays or gamma rays, electron-positron bremsstrahlung is produced by the interaction of only two particles and does not involve the decay of an unstable nucleus.
Electron-positron bremsstrahlung is caused by the acceleration of the electron and positron as they interact with each other's electric fields. This acceleration results in the emission of electromagnetic radiation.
Electron-positron bremsstrahlung has various applications in fields such as medical imaging, materials science, and particle physics research. It is also used in industrial processes, such as sterilization and material modification.
Electron-positron bremsstrahlung can be detected using specialized detectors, such as scintillation detectors or solid-state detectors. These detectors measure the energy and direction of the emitted radiation, allowing scientists to study the properties of the electron and positron interaction.
