Precise Neutron Magnetic Form Factors ⋆
Precise data on the neutron magnetic form factor Gmn have been obtained with measurements of the ratio of cross sections of D(e, en) and D(e, ep) up to momentum transfers of Q= 0.9 (GeV/c). Data with typical uncertainties of 1.5% are presented. These data allow for the first time to extract a precise value of the magnetic radius of the neutron.
متن کاملTheoretical Aspects of Neutron Magnetic Form Factors
The calculation of magnetization densities in solids is reviewed. The atomic model is still a useful first approximation while the more involved band structure approach is required for first principle calculations of solid state spin densities. The calculation of orbital contributions, either induced by an applied field or caused by spin-orbit coupling, is discussed.

In this paper an overview of past and future measurements of the elastic nucleon and deuteron electromagnetic form factors and a comparison with a selection of theoretical descriptions is provided.
متن کاملMedium Modi cations of Neutron Electromagnetic Form Factors
We propose to investigate possible medium modi cations of neutron electromagnetic form factors by measuring recoil polarizations for the semi-inclusive quasifree He(~e; e~n) reaction at Q = 1:0 (GeV/c). Requirements Beam energy : 1.645 GeV Beam polarization : 80% Beam current : 20 A Target : 15 cm cryogenic helium Luminosity : 4 10 cm 2 s 1 Detectors : Hall C HMS + neutron polarimeter Beam time...
