The discussion focuses on the generation of secondary photons in He-3 detectors, specifically addressing whether protons produced from the He(n,p)t reaction emit secondary X-ray photons as they decelerate in matter. It is established that the combined energy of the proton and triton is 764 keV, with 573 keV allocated to the proton. The secondary photons emitted are low in energy, while more energetic gamma-rays and X-rays can originate from interactions with the detector's metal wall or anode. The discussion emphasizes the importance of understanding the emission spectra of hydrogen and helium in this context.
PREREQUISITESPhysicists, radiation detection engineers, and researchers in nuclear science focusing on neutron detection and photon emission phenomena.
Think about the ionization energies of hydrogen (13.6 eV) and helium (1st 24.6 eV, 2nd 54.4 eV) so they will be UV or very soft X-rays, which would not ionize He atoms. Look at the emission or line spectra of H and He.Neutroniclad said:When the He(n,p)t reaction occurs, will proton cause any secondary x-ray photons since it de-accelerates in matter.
