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 ηd = 0.0238. This agrees well with the phenomenological value ηd = 0.0256±0.0004 quoted by Kamionkowski and Bahcall (Astrophys. J. 420, 884 (1994)).
