Compare the effective range of the strong nuclear force with that of the weak nuclear force. What does that tell you about the relative masses of the exchange particle(s) associated with these two forces? What should be the approximate (numerical) ratio of their masses (weak exchange particle to strong exchange particle)?
Answer to relevant QuestionsExplain how you can distinguish between a hadron and a lepton based on their interactions and exchange particles. Successful unification of the electromagnetic force with the weak force led physicists to what surprising conclusion about the proton? Describe how you might experimentally detect this prediction. 226Ra decays and emits a 4.706-MeV alpha particle. Find the kinetic energy of the recoiling daughter nucleus from the decay of a stationary radium-226 nucleus. Show that the disintegration energy for decay is Q = (mp – mD – me)c2 = (Mp – MD)c2, where the m’s represent the masses of the parent and daughter nuclei and the M’s represent the masses of the neutral atoms. How long is the conservation of energy “violated” in a neutral pi–meson exchange process?
