Why do you expect a higher binding energy?

It is an odd/odd nucleus.

Thanks for reply
Because average binding energy of nuclei is near about 7 Mev

Only for larger nuclei.

Thread 'How Can Photons Be Massless Yet Have Energy According to Einstein's Equations?'

Since E = mc^2, how can photons be massless? If a photon has no mass, then, according to Einstein's formula, its energy is given by E = 0 x c^2, which is 0. Yet, photons do have energy. This seems to be a complete contradiction. Please explain! Thank you.
