SUMMARY

The discussion centers on the calculations of alpha particle scattering and energy, specifically for aluminum (Al) and gold (Au). The participant calculated the scattered angle and kinematic factors but seeks validation of these calculations. They also computed the energy of the alpha particles using the formula E (Alpha) = stopping power x depth, resulting in 125 keV. However, they require assistance in determining the maximum and minimum scattered energy values.

PREREQUISITES
  • Understanding of alpha particle scattering principles
  • Familiarity with kinematic factors in particle physics
  • Knowledge of stopping power in materials
  • Basic proficiency in energy calculations related to particle interactions
NEXT STEPS
  • Research the formulas for maximum and minimum scattered energy in alpha particle interactions
  • Study the concept of stopping power in various materials
  • Explore kinematic equations relevant to particle scattering
  • Learn about experimental methods for measuring alpha particle scattering angles
USEFUL FOR

Students and researchers in nuclear physics, particle physicists, and anyone involved in experimental physics focusing on alpha particle interactions and energy calculations.

Hi,

I calculated the scattered angle & the kinematic factors for both Al & Au to be

Is what I did right?

E (Alpha) = stopping power x depth
= 250 x 0.5 = 125 keV
As for the maximum & the minimum scattered energy i didn't know how?
