Question: For a given Q value and incident particle called a
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 versus tar-get mass ranging from target masses on the order of the incident mass to target masses much greater than the incident mass. What is the threshold energy if MA >> ma? Explain what this means physically.
Answer to relevant QuestionsWhat are some of the important differences and distinctions between baryons and mesons? Explain why there are both density and temperature requirements to sustain a viable fusion energy plant. Why are these requirements at odds with one another? (a) In power reactors, using water as a moderator (“neutron slower”) works well, because the proton and neutron have nearly the same mass. Explain why this is true. (b) From your reasoning in part (a), it follows that in ...Show that the disintegration energy for decay is Q = (mp – mD – me)c2 = (Mp – MD – 2me)c2, where the m’s represent the masses of the parent and daughter nuclei and the M’s represent the masses of the neutral ...If the (electron) neutrino mass were 6.0 x 10-6 MeV, what is its speed if its total energy is 0.50 MeV?
