During a particular decay sequence in a decay chain, a nucleus first decays by alpha emission, followed by a emission, and lastly a gamma- ray emission. Compare the number of neutrons, protons, and nucleons in the final nucleus to that in the initial nucleus. How would your answer differ if the decay had occurred before the alpha decay, with the gamma emission still coming at the end? Explain.
Answer to relevant QuestionsNuclide A has a decay constant that is half that of nuclide B. Samples of both types start with the same number of undecayed nuclei, N. In terms of N, after two of A’s half-lives have elapsed, (a) How many of type A have ...Compared to 3He, the probability of absorbing a neutron is much less likely for 4He. Explain this using what you know about odd– even proton and neutron numbers.
