Question: A v bare can interact with a proton in a target
A v-bare can interact with a proton in a target of water (although this is very rare). The reaction is essentially the inverse of β–decay; that is, the proton is converted into a neutron. Neutrino experimenters can detect this reaction by using detectors. The neutrino “signature” occurs when the detector simultaneously records a -ray with energy of 2.22 MeV and two others each of 0.511 MeV. Write the reaction and explain where the three y-rays come from.
Answer to relevant QuestionsIn beta decay, explain why the beta particle kinetic energy must be less than the Q value of the decay. For a given Q value and incident particle (called a), how does the threshold energy required to initiate a specific nuclear reaction vary as the mass of the target (called A) changes? Sketch a graph of threshold energy ...Complete the following nuclear reactions: Fill in the missing blank: (a) 21H + 21 H ( 32 He + _____, (b) 21 H + 31 H ( _____+ in. (c) Find the energy released in each. (a) Assuming the range of the nuclear force to be 1.0 x 10-15m, predict the mass (in kilograms) of the exchange particle related to this force. (b) Convert the answer into the particle’s rest energy (in MeV) and identify ...
