Factorization of nuclear formfactors
V. A. Danilenko

There are some cases in which one can use a model of binding alpha-particles in order to describe the structure of the nuclei. It can also useful for identifying the properties of the elastic scattering of the electrons. It is known nowadays that light nuclei (up to calcium) have a cluster structure – an alpha-particle structure.
At the describing the elastic scattering of the electrons one can find it appropriate to express the elastic scattering differential cross section through the formfactor. If we consider electrons it is a charge formfactor.  Formfactors in the case of cluster structure can be factorized as two multipliers: one for distribution of clusters in nuclei and the second for the cluster formfactor itself. 
The light nuclei consist of alpha-particles and the formfactor (spherical Bessel function) represents a spherical shell made of alpha-particles. We consider two possible types of the alpha-particle distribution – surface and volume distribution. In the first case the formfactor will be proportional to the spherical Bessel function of order zero and in the second case it will be proportional to the spherical Bessel function of order one.
The research covered two reactions e+^16O and e+^12C at different energies.
