When &alpha; = 0, the scaling is said to be of the Bohm type, and when &alpha; = 1, of the gyro-Bohm type.

The ELMy H-mode scaling is of the gyro-Bohm type.
The ELMy [[H-mode]] scaling is of the gyro-Bohm type.
Gyro-Bohm scaling is what one would expect for diffusive transport based on a diffusive scale length proportional to &rho;<sub>i</sub> (the ion gyroradius).
