How Do You Calculate Binding Energy with the Weizsacker Formula?

[kraigandrews]

Homework Statement

For ⁵⁸Ni:
B(AZX) = aVA - aAA^2/3 - aC[Z(Z-1)]A^-1/3 - aS[(N-Z)^2]/A + δ.
Using the parameter values given by Enrico Fermi (aV = 14 MeV, aA = 13 MeV, aC = 0.72 MeV, aS = 19 MeV, ∆ = 33 MeV · A-3/4), determine each term in the formula.

Calculate the magnitude of the surface energy.

Determine the magnitude of the Coulomb energy.

What is the magnitude of the symmetry energy?

What is the total binding energy according to the Weizsacker formula?

What is the binding energy of the nucleus using the table of atomic masses ?

The Attempt at a Solution

For Nickel:
A=58
Z=28
N=30

Using the given parameters I think it would be a simple plug in on each term to find the wanted energies. So I am not sure why it won't work.

yes i believe they are just plug ins

i am just curious why is your delta term 33MeV x A^-3/4

i checked wiki it says 11MeV x A^-1/2
