The Coulomb sum of 7Li
The experimental values of longitudinal response function of the 7Li nucleus have been obtained and these results have been used as the basis to find the Coulomb sum values at momentum transfers ranging from 0.55 to 1.625 fm-1. The obtained experimental Coulomb sum values have been used to determine...

| Summary: | The experimental values of longitudinal response function of the 7Li nucleus have been obtained and these results have been used as the basis to find the Coulomb sum values at momentum transfers ranging from 0.55 to 1.625 fm-1. The obtained experimental Coulomb sum values have been used to determine the total Coulomb energy of the 7Li nucleus. The result of the comparison of the Coulomb energy for the 7Li nucleus with the Coulomb energies for the 6Li and 4He nuclei a) is consistent with the paradox (revealed in the elastic electron scattering experiment) that the 7Li rms charge radius is smaller than the one of the 6Li nucleus; b) leads to the conclusion that, within the framework of the two-cluster model of the 7Li nucleus (α + t), the size of the α-cluster should be larger than the one of the 4He nucleus. |
