摘要：

The effect of unequal neutron and proton masses on the binding-energy difference of He3 and H3 is calculated using a wide variety of nuclear models. We find that this charge-symmetry-breaking mechanism contributes 14(2) keV to the 764 keV difference. We also demonstrate the importance of the mixed-symmetry wave function components in making the contribution of this mechanism fairly small, but rather model dependent. © 1990 The American Physical Society.
