question 1 \
A certain radionuclide is being manufactured in a cyclotron at a
constant rate R = 3.80 ×
1021 h-1. It is also decaying with
disintegration constant λ = 0.0917 h-1. After
a time that is long compared to the half-life how many undecayed
nuclei are there? The nuclide is said to be in secular
equilibrium with its source; in this state its decay rate
is just equal to its production rate.
question 2
Nuclear radii may be measured by scattering high-energy
electrons from nuclei. (a) What is the
de Broglie wavelength for 229 MeV
electrons? (b) Are these electrons
suitable probes for this purpose?
Thank you.
