My mistake about the transverse/longitudinal masses. I guess I was referring to the density of states effective mass (or whatever the mass that can be determined from the dispersion curves is called).
But according to Wikipedia:

Hey there.
I have a question concerning the effective masses in silicon. From what I've learned, the effective masses of electrons and holes can be determined from the curvature of the dispersion curve at the extrema. Since the effective mass is inversely proportional to the second derivative...
