Attempts have been made to quantitatively recover the neutron magnetic moment from first principles.
2.
The measured values of " g " ( s ) for the neutron and the proton are twice their magnetic moment ( either the neutron magnetic moment or the proton magnetic moment ).
3.
In collaboration with the Institut Laue Langevin, Ramsey also worked on applying similar methods to beams of neutrons, measuring the neutron magnetic moment and finding a limit to its acoustic evidence did not indicate the presence of a second gunman's involvement in the assassination of President John F . Kennedy.
