WebMar 10, 2024 · Like all other subatomic particles, photons exhibit wave-particle duality, meaning that sometimes they behave as tiny particles and sometimes they act as waves. … WebThe mass of a proton is approximately 1,835 times that of an electron (m p = 938MeV, m e = 0.511MeV). As a result, protons tend to travel in straighter paths than electrons. Bragg Peak Because energy loss by Coulomb interaction is proportional to 1/v 2, a large portion of a charged particles energy is lost near the end of its path.

WebReal photons are measured in two varieties of electromagnetic calorimeter (see Fig. 3 ). Because virtual photons of mass M decay in times of order ℏ/ M to “di-lepton pairs” consisting of e+e− or μ + μ −, they are detected in PHENIX via charged particle spectrometers which specialize in electron or muon measurements.
