How long is the conservation of energy “violated” in a neutral pi–meson exchange process?
Answer to relevant QuestionsDetermine what the daughter nuclei would be in each of the following decays. Can any of these decays occur spontaneously? Explain your reasoning in each case. (a) The quark combination for an antiproton is (1) uud, (2) udd, (3) uud, (4) udd. (b) Prove that your answer to part (a) gives the correct electric charge for the antiproton. Complete the following nuclear reactions and find their Q values (use Appendix V for masses if necessary): The predominant mode of decay for the charged pions is into a muon and a neutrino. The positive pion results in the neutrino and the negative pion in the antineutrino. (a) Write the decay equations of both charged pions, ...Is the reaction endoergic or exoergic? Prove your answer. (The reaction on page 1003 gives the mass values.)
