Homework Statement
If a neutron is confined to the nucleus, its wave function
– and therefore the probability of finding it at a certain position – has a
characteristic width, Δx, equivalent to the nucleus diameter. What is the uncertainty
in the neutron momentum Δp as a function of atomic mass number
A? What energy would a neutron with momentum
p equivalent to the momentum uncertainty Δp correspond to (justify using a
non-relativistic approximation) in MeV?
Homework Equations
r=(n^2h^2ε0^2)/(πmeZe^2); ΔxΔp>h
The Attempt at a Solution
My guess is that in order to find an expression for Δp in terms of A I should use Bohr radius equation but I'm not sure how to go from there
