Q# 4 (a) A beam of 8.3 MeV alpha particles is directed at an aluminum foil. It is found that the
Rutherford scattering formula ceases to be obeyed at scattering angles exceeding about 60°. If the
alpha-particle radius is assumed small enough to neglect here, find the radius of the aluminum
nucleus.
Find the fraction of 7.7-MeV α particles that is deflected at an angle of 90° or more from a gold foil of 10 -6 m thickness.
Gamma-ray detectors like the one described in the preceding problem often use calorimetry to determine gamma-ray energies. Suppose a beam of 100-MeV gamma rays strikes a target with a mass of 2.5 kg and specifi c heat 430 J/(kg # K). How many gamma rays are needed to raise the target’s temperature by 10 mK?
