In a Rutherford scattering experiment, an α-particle (charge = +2e) heads directly toward a lead nucleus (charge = +82e). The α-particle had a kinetic energy of 4.5 MeV when very far (r → ∞) from the nucleus. Assuming the lead nucleus to be fixed in space, determine the distance of closest approach (in fm). Hint: Use conservation of energy with PE = keq1q2 r . answer in ______ fm

Modern Physics: Experimental basis for quantum theory + Atomic models The actual size of a gold nucleus is approximately 7 fm. Knowing this, calculate the kinetic energy (KE, or KEa, however you may choose to label the measurement) that an alpha particle would need to just touch the outside of the nucleus. Does this seem like a reasonable number? Hint - the LHC is currently the most powerful particle accelerator on Earth, and i?t operates at 13 TeV (TeV =...
