Q. 24.4( 37 Votes )

Suppose you are given a chance to repeat the alpha-particle scattering experiment using a thin sheet of solid hydrogen in place of the gold foil. (Hydrogen is a solid at temperatures below 14 K.)

What results do you expect?

Answer :

In alpha-particle scattering experiment, if we use a thin sheet of solid hydrogen in place of the gold foil, then the mass of Hydrogen will be lesser than that of incident alpha particle and the scattering angle will be not large enough. As mass of the scattering particle is more than the target nucleus, the alpha particles will not bounce while using solid Hydrogen.
