Maximum energy transefer in COmpton effect - rutherford

Click For Summary
SUMMARY

The discussion focuses on calculating the impact parameter of a 4.57 MeV alpha particle detected at a 52.4-degree angle in a Rutherford scattering experiment. The user employs the formula b = (rmin/2)cot(theta/2), where rmin is calculated using the equation rmin = Z1Z2e^2/4πEok. The user arrives at a value of 3.46 × 10^-15 meters for the impact parameter, using constants such as the charge of the electron and the Coulomb's constant. The calculations are confirmed to be on the right track, indicating a solid understanding of the principles involved.

In the Rutherford scattering experiment a very thin gold foil target is bombarded with a beam of a particles of known kinetic energy. A detector which can be moved on a circle around the target counts the scattered particles. What was the impact parameter of a 4.57 MeV a particle if it was detected at 52.4 degree angle?

Im using b= (rmin/2)cot(theta/2) where rmin = Z1Z2e^2/4piEok

so i have ((2)(79)(1.6*10^-19 c)^2 / (4.57 *10^6 eV)(1.6*10^-9 J/eV) ) * 8.99*10^9 Jm/c ...and got 3.46 *10^-15 is this right so far? ...i got 8.99*10^9 by (1/4piEo) ...thanks

DO NOT DOUBLE POST!:mad:This is a HW problem anyway.

my bad figured more exposure i would get quicker response
