From our class notes I have:

Please could someone explain how he manages to get a single parabola from the pairing term? All I understand about the pairing term is that aBy keeping A constant and varying Z there is generally only one stable nuclide for each odd value of A. We can show this by looking at the pairing term to show that odd A gives a single parabola with a single minimum.

_{p}<0 for Z,N even, even. a

_{p}=0 for A odd and a

_{p}>0 for Z,N odd, odd.

At a loss if anyone can help?
