... VYukawa(r) = exp(- mc2 r / !c) / r, where m is the mass of the exchange particle. Note that as the mass goes to zero, we regain the usual 1/r potential. The range of the interaction is given by !c/ mc2. Thus the range of pion exchange, for example, is about 1.4 fm. The interaction between nucleons i ...

Because each chemical element corresponds to precisely one value of the atomic number, nuclides can also be identified by the symbol for the element followed by the mass number (i.e. without also specifying the atomic number). For example, instead of 146 C we can write C-14 or Carbon-14. Write ea ...
