“…We considered the model when α-particles are whithin some surface shell. To certain extent this is a variant of the surface well model [7]. Assuming the quasicristaline structure of α-particles in nuclei we considered two possible types of α-particle density distribution, namely surface and volume distributions.…”

We considered folded formfactors for the clusterized light nuclei. Having assumed a gaussian form for the alpha-particle formfactor, charge and nuclear formfactors were factorized in two parts: one for alpha-particle and another one for the alpha-particle distribution in the nucleus. Applications to electron and heavy ion scattering are considered. IntroductionIn the past years experimental technique like the one with inverse geometry [1] provided a new information on the excitation functions, as well as on spin and parity assignments. Previously elastic scattering of electrons as projectiles has been used to study the charge density distributions and charge radii. On the other hand, heavy ions were used to investigate nuclear matter and potential generating wave functions in the elastic channel. Today we know well that light nuclei up to calcium have a cluster structure, namely alpha-particle structure. At certain conditions the scattering amplitude can be expressed through the formfactor. In the case of electrons it is a charge formfactor, while in case of heavy ions it is a nuclear formfactor. In both cases these 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 by itself. Charge formfactorsConsidering high energy electrons as a probe it is worth noting previous attempts to extract information about cluster structure [2]. The role of cluster configurations in the nucleus was investigated in [3]

The repulsion due to the nonlinearity of a Schr6dinger equation for the elastic scattering of heavy ions is approximated by the compression energy stored in the region of contact of two colliding liquid drops with trapezoidal densities. Qualitative and quantitative estimates show the required repulsion to be in line with literature results. The absolute maximum for the projectile energy at which our model is still expected to be applicable is given by Er<6 MeV.
