摘要：

The effects of the presence of weakly interacting light boson (WILB) in neutron star matter have been revisited. Direct checking based on the experimental range of symmetric nuclear matter binding energy(1) and the fact that the presence of this boson should give no observed effect on the crust properties of neutron star matter, shows that the characteristic scale of WILB (g(2)/mu(2)) should be <= 2 GeV-2. The recent observational data with significant low neutron stars radii(2) and the recent largest pulsar which has been precisely measured, i.e. J1903+ 0327 (Ref. 3) indicate that in-medium modification of WILB mass in neutron stars cannot be neglected.
