Abstract: (Elsevier)
In the σ - ω model, the nucleon size in a nuclear medium is different from that in free space. The modification is due to the change of the vacuum structure. The mean square radius of the proton is swollen by (− 1 2π 2 )( g ω m 0 ) 2 In M ∗ M , where g ω , m 0 and M ∗ denote the ω -N coupling constant, the bare mass of the ω -meson and the nucleon effective mass, respectively. This increases the RMS radius of the proton in the normal-density nuclear matter by 7.6%. As a result nuclear response functions for electron scattering are reduced by 10–15% at the squared four-momentum transfer 0.2–0.3 GeV 2 .- NUCLEON: MODEL
