  The two leading twist, quark helicity conserving generalized parton
distributions (GPDs) of 3He, accessible, for example, in coherent deeply
virtual Compton scattering (DVCS), are calculated in impulse approximation
(IA). Their sum, at low momentum transfer, is found to be largely dominated by
the neutron contribution, so that 3He is very promising for the extraction of
the neutron information. Anyway, such an extraction could be not trivial. A
technique, able to take into account the nuclear effects included in the IA
analysis in the extraction procedure, even at moderate values of the momentum
transfer, is proposed. Coherent DVCS arises therefore as a crucial experiment
to access, for the first time, the neutron GPDs and the orbital angular
momentum of the partons in the neutron.
