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
Grover (given name) Grover (given name) Grover is a masculine given name. Grover first became popular as a given name in the United States during the presidencies of Grover Cleveland, in part of a long-standing American trend of naming babies after presidents. Cleveland's official first name was Stephen; he was named after Stephen Grover, a former minister at the church his parents attended.
