Effect of quadrupole correlations in light nuclei

摘要: Abstract Quadrupole correlations of nucleons having equal energies are considered on the basis effective Hamiltonian describing interaction nucleon pairs. It is shown that formation quadrupole in light nuclei energetically favoured if among pairs attractive. Certain laws binding energy last neutron explained by taking into account pair and correlations. A criterion obtained shows at what excess number neutrons over protons stable nuclei, as a result parting Fermi surfaces, some outer cease to participate quadruple correlations, which leads disappearance explicit α-particle properties nuclei.
