12.2 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?

    12.2 In the alpha-particle scattering experiment, if a thin sheet of hydrogen is used in place of a gold film, then the scattering angle would not be large enough. This is because the mass of hydrogen (1.67 * 10 - 27 kg) is less than the mass of incident  ? - particles (6.64 * 10 - 27 kg). Thus, the mass of the scattering particles is more than the target nucleus (hydrogen). As a result, the ? - particles would not bounce back if solid hydrogen is used in the ? - particle scattering experiment.
