The criterion of stability against radial adiabatic oscillations is considered for the models of neutron homogeneous stars in the framework of general relativity. The critical value of adiabatic exponent $\gamma_{cr}$ is obtained in the framework of general relativity, which corresponds to the limit of stability of the star and is applicable in the whole allowable range where the parameter $\eta_1 =R/\alpha$ ($R$ – star radius, $\varepsilon$ – energy density, $\alpha=\sqrt{3c^4/(8\pi G\varepsilon)}$) varies. The obtained results are compared with the known result of Chandrasekhar.
