Charge radius the composite particle must be modeled as a sphere of negative rather than positive electric charge for the interpretation of electron scattering experiments. In these cases, the square of the charge radius of the particle is defined to be negative, with the same absolute value with units of length squared equal to the positive squared charge radius that it would have had if it was identical in all other respects but each quark in the particle had the opposite electric charge (with the charge radius itself having a value that is an imaginary number with units of length). It is
Finn (given name) Finn (given name) Finn is generally regarded as a masculine given name. The name has several origins. In some cases it is derived from the Old Norse personal name and byname "Finnr", meaning "Lapp" or "Finn". In some cases the Old Norse name was a short form of other names composed with this element. In other cases, the name "Finn" is derived from Irish, meaning "white" or "fair". In the later case, the name is an earlier Irish variant of "Fionn". It is also occasionally a female given name, although this is less common. People with the given name include:
