Photon atomic mass
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. WebApr 18, 2014 · The variation of the effective atomic numbers of the low- Z materials with photon energy is shown in Figures 1 (a), 1 (b), 1 (c), 1 (d), 1 (e), 1 (f), 1 (g), and 1 (h). The effective atomic numbers below 10 keV were not compared due to large uncertainty in Auto- [ …
