Rutherford Scattering
A great deal of what is known about the atomic nucleus has been deduced from the analysis of scattering experiments done with charged particles and neutrons. The first such experiments were performed with alpha particles from naturally radioactive substances, the counting of the scattered particles being done by visual observation of the scintillations (faint flashes of light) from a zinc sulfi...
متن کاملRutherford Scattering of α-Particles
The scattering of α-particles off of gold foil was investigated. Attenuation of the α-particle beam was used to measure the thickness of the gold foil used. The coefficient of the Rutherford differential scattering cross section was experimentally determined to be (7.81 ± 5.35) × 10−25cm2, compared to 1.76 × 10−24cm2, with a reduced chi-squared of 3.4, which is a reasonable fit and confirms the...
متن کاملRutherford Scattering with Retardation
Numerical solutions for Sommerfeld model in nonrelativistic case are presented for the scattering of a spinless extended charged body in a static Coulomb field of a fixed point charge. It is shown that differential cross section for extended body preserves the form of the Rutherford result with multiplier, not equal to one (as in classical case), but depending on the size of Sommerfeld particle...

متن کاملDetection of hydrogen by electron Rutherford backscattering.
A novel method for detection of hydrogen by an electron beam in extremely thin samples is described. Elastically scattered electrons impinging with 20-30 keV on a thin formvar film were detected at a scattering angle near 45 degrees. In these large momentum transfer elastic collisions a clear separation of the signal of hydrogen and heavier elements was found. By changing the momentum transfer ...
