Popis:	The electrodisintegration of He3 is considered focusing on the effects of the Δ isobar excitation which is treated dynamically on the same footing as nucleons. In the region beyond the quasi-elastic peak the predicted transverse response functions RT and RT′ are visibly affected. This leads to sizable Δ isobar effects for inclusive and exclusive electron polarization asymmetries in particular kinematic regions. A measurement performed in the proposed regime could provide judgment for models of nuclear forces and currents.
