Main Question or Discussion Point
Hello! Can someone point me towards some papers/readings providing formulas (derived theoretically or based on experimental data) for the nuclear charge radius? Almost all the papers where I found a formula for that are of the form ##aA^b+c##, where a, b and c are constants and A is the mass number (N+Z) of the given nucleus. I guess these work well in certain situations, but the formula is obviously wrong (switching the number of protons and neutrons gives the same value of A, but obviously the charge radius will be very different). So are there some formulas more general (and hence hopefully closer to the true formula)? Thank you!
