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
Alan (given name) is today Russia, and who were known to Classical writers in the 1st century CE. According to historian Bernard Bachrach, the Alans settled in parts of what is today France, including Brittany, in the Early Middle Ages. Bachrach stated that the use of forms of the name in given names, surnames, and place names, are evidence of the continued influence of the Alans on the Gaulish, Breton and Frankish peoples. The Breton name "Alan" can not be a direct loan from the ethnic name of the Alans (rendered as "Alānī" or "Halānī" in Latin, from Scytho-Sarmatian "*Al[l]ān-", derived from Old
