A beam of particles strikes a wall containing 2 × 10^29 nuclei
per m^3 . Each nucleus behaves like a sphere of radius 3 × 10^−15
m. Find the thickness of a wall that exactly half the particles
will penetrate without scattering. What thickness would be needed
to stop all but one particle in 10^6 ?
Please explain all the steps?
