Abstract
The D-wave state component of the neutron-proton bound state in the
deuteron is calculated in the Nambu-Jona-Lasinio model of light
nuclei-the relativistically covariant quantum field-theoretic
approach to the description of low-energy nuclear forces. The
theoretical value of the fraction of the D-wave state relative to the
S-wave state is equal to
. This agrees well
with the phenomenological value
quoted by Kamionkowski and Bahcall (Astrophys. J. 420, 884 (1994)).
