Problem

Three particles move through identical

1.0\,\text{nm}

-wide channels. • Particle A: electron, speed

2.0\times10^{6}\,\text{m}\,\text{s}^{-1}

• Particle B: neutron, speed

2.0\times10^{3}\,\text{m}\,\text{s}^{-1}

• Particle C: buckyball (C

_{60}

) molecule of mass

1.2\times10^{-24}\,\text{kg}

, speed

200\,\text{m}\,\text{s}^{-1}

Rank the three particles from most likely to least likely to exhibit quantum diffraction within the channel and briefly justify your ranking.
