Given initially 40mg of radium-226 (one of the decay products of uranium-238), determine,
(a) The amount that will be left after 500years.
(b) The number of α particles the radium will have emitted during this time, and
(c) The amount of kinetic energy that will have been released.
(d) Find the decay rate of the radium at the end of the 500 year.
Question:Why might a flat-bottom finite well be a better approximation of the potential well confining nucleons than a Coulomb well tapering to a lowest energy in the middle
Oxygen-19decays. What is the daughter nucleus, and what may be said of the kinetic energy of the emitted particle?
Consider equal numbers of deuterium and tritium nuclei fusing to form helium-4 nuclei, as given in equation,
(a) What is the yield in joules of kinetic energy liberated per kilogram of fuel?
(b) How does this compare with a typical yield of for chemical fuels?
