摘要：
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 eta (d) = 0.0238. This agrees well with the phenomenological value eta (d) = 0.0256 +/- 0.0004 quoted by Kamionkowski and Bahcall (Astrophys. J. 420, 884 (1994)).
