A mineral is biaxial positive if β is closer to α than to γ.; In this case the acute angle, 2V, between the optic axes is bisected by the γ refractive index direction. Thus we say that γ is the acute bisectrix (BX A), because it bisects this angle.; If a table of optical properties of minerals reports the 2V angle, it usually refers to this acute angle.
