On the Correlation between the Deuteron Quadrupole Moment, the Deuteron Asymptotic D/S Ratio, and the S-Wave Normalization Constant

摘要

The correlation between the deuteron quadrupole moment Q, the deuteron asymptotic D/S ratio η, and the deuteron asymptotic normalization constant AS is studied. For local nucleon–nucleon potentials, it was found that the quantities Q/η and A_(~2_S) are related by a linear equation. Owing to this, the deuteron quadrupole moment Q can be determined from known values of AS and η with an absolute precision of about 0.0003 fm~2. The inclusion of the correction for meson-exchange currents and the use of the experimental neutron–proton phase shifts from the GWU partial-wave analysis made it possible to estimate the deuteron quadrupole moment at Q = 0.2852 fm~2, which is in good agreement with experimental data.
