# What is the Lorentz factor γ value in order to find the Larmor precesion frequency for the electron including the Thomas precesion correction?

I want to calculate the Thomas corrected value for the lab frame of the electron's Larmor precesion frequency using this equation:

$$\omega_{s(g=2)}=\frac{e B}{m c \gamma}$$

I don't know what Lorentz factor value γ to input?

I can't find any reference to this problem.
