E1polarizability ofLi7and astrophysicalSfactor forHe4(t,γ)7Li

Abstract
The electric dipole polarizability of Li7 is studied theoretically. A consistent interpretation is obtained among the electric dipole polarizability, the quadrupole moment, the tensor analyzing powers for aligned Li7 scattering at sub-Coulomb energies, and the radiative capture (or photodis- integration) cross section for the 3H+α→7Li+γ reaction.
