A lithium ion Lit++ (Z = 3, A = 6g/mol) with incident kinetic energy EK = 7.5MEV is scattered on
a gold nucleus (Z = 79, A = 197g/mol) through an angle of 10°. Assume that the mass of the lithium
ion is much smaller than the mass of the gold nucleus. Please answer the following questions:

An atom in an excited state has a mass of 63.332 and then decays to a mass of 63.329 amu by emitting 3 x-rays of equal energy. a) What is the energy (in keV) and wavelength of each x-ray? b) If one of these X-rays is absorbed by a neighbouring atom and ejects a K-shell electron, what is the velocity of the electron? (note: K-shell binding energy is 43 keV)
In a Rutherford scattering experiment, an a-particle (charge = +2e) heads directly toward a gold nucleus (charge = +79e). The α-particle had a kinetic energy of 5.0 MeV when very far (r→ ∞) from the nucleus. Assuming the gold nucleus to be fixed in space, determine the distance of closest approach. Hint: Use conservation of energy with PE =kq1q2/r.
