(5-20) In Question 5-15, we derived an expression for the localisation energy:
Ek = 3h2/32mπ2<r>2
Use this to investigate how far Cormorant’s suggestion might explain the mysterious smallness of a proton. You’ll need to know some approximate numbers:
Proton mass ≈ 2000 x electron mass
Mean distance of electron from nucleus ≈ 100,000 x radius of nucleus
