A combination of two earlier models of this thing that incorporates vibration and rotation is the so-called collective model.
A combination of two earlier models of this thing that incorporates vibration and rotation is the so-called collective model. A correction term in a formula for these things adds or subtracts a term equal to 11.18 MeV over A to the one-half for even-even and odd-odd types of them, respectively. That formula, developed by Carl Friedrich von Weizsaecker, incorporates empirical data and assumes that this thing behaves as an incompressible liquid drop, and is used to calculate the binding energy of these things, which is the energy needed to (*) split them into multiple parts. These things are more stable when their constituents are present in so-called "magic numbers". Its existence was confirmed by the results of the gold foil experiment. For 10 points, what part of the atom consists of protons and neutrons?
