well ...
we are studying bethe and weiszacker semi empiric formula , and i am confused . specifically about the third term the asymmetry term and how it lowers the binding energy .
so just so i know that i am getting this straight , originally the binding energy no matter the nucleus is constant but there variable that change the effective energy used for binding , like the second term which is the Colombian term , part of the energy is wasted fighting the repulsion between the protons , for the asymmetry term , it is explained with the pauli exclusion , saying that the surplus of neutrons have a higher energy than protons , yeah so what ?
i tried using how an electron being in a higher level of energy is less bound to the nucleus as an analogy but it doesn t make complete sens either.
since the binding energy given to each nucleus is constante , and the energy actually used for binding is less than it should be , then where does the energy go ? what is it used for ? is it used to make the protons have a higher energy to bind with the neutrons ? or is it what it gives the neutrons higher energy in the first place and pauli s exclusion principle just means that they could do that ?
i am so confused , and i am sorry if i am not being clear enough , thank you very much in advance
