Cluster form factors in light nuclei

Full text: A successful description of electron elastic scattering on light nuclei in the frame Brink model also Ikeda diagram of light nuclei and dying behavior of cluster wave functions in the intrinsic region of nuclei brought us toward idea of quasicrystalline nuclear structure. Phonon excitations of quasicrystal are connecting with appearance energy bands. Form factors extracted from the experiments can be factorized as a production of a cluster form factor and density distribution of clusters. The last one contains the periodicity of the quasicrystalline grate. According to the calculations this periodicity takes place when De Broglie wave of cluster is comparable with the distance between clusters
