Suppose you are given a chance to repeat the alpha particle scattering experiment using a thin sheet of solid hydrogen in place of gold ofil (hydrogen is a solid at temperature below 14 K). What results do you expect?

Answer»

SOLUTION :The basic purpose of scattering experiment is defeated, because solid hydrogen will be a much ligther target compared to the alpha particle acting as projectile. According to theory of ELASTIC collisions, the target hydrogen will move much FASTER compared to alpha, after the COLLISION. We cannot determine the size of hydrogen NUCLEUS.
