(5-20In 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
