2. Estimate the relative size of the pulses produced at the output of a photomultiplier tube in a scintillation counter, when 1 MeV and 3 MeV grays are absorbed in it?

5. An XPS with an instrument work function of 4.5eV was used to analyze a surface. An observed kinetic energy of 795.2 eV was observed when a(n) MgKα (1253.6 eV) X-ray source was used. What was the binding energy of the electron coming from this surface?

9) Calculate the deBroglie wave of a particle traveling at 4.66 e 6 m/s and has a mass of 1.94 e -19-Kg

3. a) Alpha particles of the same initial speed are shot at the same intensity toward gold, silver, and aluminum foils of the same thickness. They are observed at a detector at a fixed scattering angle, 0 0°. What would the ratios of the number of alpha particles scattered by the gold and silver foils to the aluminum foil, No Au 13). NaAl and respectively, be? (ZAu = 79, ZAg = 47, ZAI Na Ag NaAl b) Compare the number of a particles of fixed kinetic energy scattered through an angle of 10° (call this Na(10°)) with the number scattered through an angle of 20° (Na (20°)) for Rutherford scattering by a thin gold foil of fixed thickness. Compute Na (10⁰) Na (20°). p2 Rutherford's scattering model assumes that the alpha particles experience a Coulomb repulsion, F = KqZe from the nucleus of the foil's atom. If, in a head-on collision the alpha particle has enough energy to get inside a uniformly charged Kqa Zer nucleus of radius R, the force law would change to F = R³ " point-nucleus…
