The lifetime of these objects can be measured using the charge plunger method. One equation describing the effect of collisions on the energies of these objects has a term of minus 2 over m times the square root of the product of masses and energies times cosine theta. Their interaction with other objects can be of a pickup or stripping nature. One formula for the energy stored by these has a term that is proportional one over the cube root of mass times z squared. A partially empirical formula for the properties of these has surface, volume, asymmetry, and Coulomb terms. Stability in these structures occurs at certain magic numbers. The Weizsacker formula for these objects is based on the liquid drop model. Their structure is described by the shell model. These small objects combine in the CNO cycle. For 10 points, name these objects made out of protons and neutrons.
