Determine the distance of closest approach when an alpha particle of kinetic energy 4.5 MeV strikes a nucleus of Z = 80, stops and reverses its direction.

Calculate the distance of closest approach when a proton of energy 3 MeV approaches a gold nucleus (Z=79).

In the Geiger-Marsden scattering experiment find the distance of closest approach to the nuclcus of a 7.7 Mev alpha -particle before it comes momentaily to rest and reverses its direction. (Z for gold nucleus = 79 )

In a geiger - marsden experiment. Find the distance of closest approach to the nucleus of a 7.7 me v alpha - particle before it comes momentarily to rest and reverses its direction. (z for gold nucleus = 79) .
