A repulsive force could

stop the collapse of the neutron star in place of neutron degeneracy pressure.

Einstein field equation gravitational potential:

[tex]\nabla^2 \phi = 4 \pi G \left( \rho + \frac{3P}{c^2} \right)[/tex]

General Relativity gravitational pressure:

[tex]P_e = \frac{c^2}{3} \left( \frac{\nabla^2 \phi}{4 \pi G} - \rho \right)[/tex]

Classical Yukawa Pressure:

[tex]P_y = f^2 \frac{e^{- \frac{r_1}{r_0}}}{4 \pi r_s^2 r_1^2}[/tex]

Einstein-Yukawa criterion:

[tex]P_e = P_y[/tex]

[tex]\frac{c^2}{3} \left( \frac{\nabla^2 \phi}{4 \pi G} - \rho \right) = f^2 \frac{e^{- \frac{r_1}{r_0}}}{4 \pi r_s^2 r_1^2}[/tex]

Is this criterion conceptually correct?

Classical Schwarzschild-Yukawa nuclear interaction strength Limit:

[tex]f_1 = \frac{r_1c^2}{2} \sqrt{\frac{e^{\frac{r_1}{r_0}}}{G}}[/tex]

[tex]r_1 < r_0[/tex]

Based upon the Orion1 equasions, what are the Standard International (SI) units for [tex]f_1[/tex] ?

[tex]\frac{c^2}{3} \left( \frac{\nabla^2 \phi}{4 \pi G} - \rho \right) = \frac{c^4}{16 \pi G r_s^2}[/tex]

[tex]\left( \frac{\nabla^2 \phi}{4 \pi G} - \rho \right) = \frac{3 c^2}{16 \pi G r_s^2}[/tex]

Classical Einstein-Schwarzschild critical density:

[tex]\rho_c = \left( \frac{\nabla^2 \phi}{4 \pi G} - \frac{3 c^2}{16 \pi G r_s^2} \right) = \frac{}{4 \pi G} \left( \nabla^2 \phi - \frac{3 c^2}{4 r_s^2} \right)[/tex]

[tex]\rho_c = \frac{}{4 \pi G} \left( \nabla^2 \phi - \frac{3 c^2}{4 r_s^2} \right)[/tex]

Based upon the Orion1 equasions, what are the Standard International (SI) units for [tex]\nabla[/tex] and [tex]\phi[/tex]?
