It is 38 degrees.
I don't know how to prove it theoretically but when done practically the answer is 38 degrees

F2 Equilateral Dispersive Prisms (385 nm - 2 µm)
Transmission data is for a 10 mm thick sample.
F2 is a flint glass that offers excellent performance in the visible and NIR spectral range. It offers a high refractive index and low Abbe number, making it excellent for use in an equilateral dispersive prism. Compared to N-SF11, it offers superior chemical resistance and slightly higher transmission.
Polarization Effects
For p-polarized light (blue line) incident on a dispersing prism at the angle of least deviation, the graph to the right shows that only a small percentage of the p-polarized light is reflected at the surface. Thus, for this polarization, the transmission through a prism fabricated from F2 will be excellent even though there is no AR coating on the surface.
