Having calculated that the momentum uncertainty, Δp, for an electron confined in a 1 dimensional box of a width, 10(adsbygoogle = window.adsbygoogle || []).push({}); ^{-15}m equivalent to a typical nuclear diameter, is (5.2x10^-20 [kg m s^{-1}] )

Knowing also that nuclei often emit electrons with energies between 1 and 10 MeV.

How do I calculate the electron's mean momentum?

thank you.
