On an inelastic form factor of the 4He 0+ resonance

A form factor of electron inelastic scattering with excitation of the 0+ resonance of the 4He nucleus have been analyzed. The collective and cluster models with Volkov nucleon-nucleon potential have been applied. It is shown that the cluster model, as distinct from the collective one, provides a good fit to the experimental momentum-transfer dependence of the form factor. This is in favor of the cluster nature of the 0+ resonance
