在二体力和三体力的BCS框架下，研究了高密度中子物质中超流相的开始。当在带隙方程中考虑强关联效应时，配对带隙在$0.1--0.4\phantom{\rule{0.28em}{0ex}}{\text{fm}}^{\ensuremath{-}3}$附近的密度范围内不为零，峰值略小于0.05 MeV。这些结果可能会限制超流性在解释中子星核心现象中的作用。
The onset of the superfluid phase in high-density neutron matter is studied within the BCS framework with two- and three-body forces. When including the strong correlation effects in the gap equation, the pairing gap turns out to be nonvanishing in a range of densities about $0.1--0.4\phantom{\rule{0.28em}{0ex}}{\text{fm}}^{\ensuremath{-}3}$ with a peak value a bit less than 0.05 MeV. These results could limit the role of the ${}^{3}{\mathit{PF}}_{2}$ superfluidity in the interpretation of phenomena occurring in the neutron-star core.
