Rutherford cross section
WebMar 29, 2024 · The essential features of Rutherford’s apparatus are shown in Fig. 20.1: α -particle emitted from a radioactive source strike a thin gold foil. Most pass straight through the foil, but a fraction are scattered at an angle θ into the detector. WebFor A/r-potentials the differential cross-section can be evaluated exactly, with the result d(2)σ dΩ = A2 16E2 1 sin4 ϑ 2, which is called the Rutherford scattering cross-section. This result was ob-tained by Rutherford in Cambridge, U.K., at the beginning of the twentieth century. At the same time he was able to confirm this formula ...

The differential cross section can be derived from the equations of motion for two charged point particles interacting through a central potential. In general, the equations of motion describing two particles interacting under a central force can be decoupled into the center of mass and the motion of the particles relative to one another. Consider the situation where one particle (labelled 1), with mass and charge with the elementary charge, is incident from very far away with some initial speed on … WebMott cross-section includes the spin effects. Mott cross-section without recoil is given by the formula, ( d σ d Ω) Mott ∗ = ( 1 − β 2 sin 2. . θ 2) ( d σ d Ω) Rutherford. The effect of spin is to reduce the cross-section as the scattering angle increases. This can be understood in terms of helicity conservation.
