Definition

quotient of gyro frequency and collision frequency in a plasma, expressed by

$H_{c} = \frac{ω_{c}}{2 π} \frac{λ}{v}$ ; where

$ω_{c}$ :: is cyclotron angular frequency (ISO 80000-10: Atomic and nuclear physics),

$λ$ :: is mean free path (ISO 80000-9: Physical chemistry and molecular physics), and

$v$ :: is average speed (ISO 80000-3: Space and time)

quotient de la pulsation cyclotron par la fréquence de collision dans un plasma, exprimé par

$H_{c} = \frac{ω_{c}}{2 π} \frac{λ}{v}$ ; où

$ω_{c}$ :: est la pulsation cyclotron (ISO 80000-10: Atomic and nuclear physics),

$λ$ :: est le libre parcours moyen (ISO 80000-9: Physical chemistry and molecular physics), et

$v$ :: est la vitesse moyenne (ISO 80000-3: Space and time)

Notes

Sometimes the inverse of this number is wrongly used.

$2 π$ times this quantity is called the Hall parameter.

Parfois, l'inverse de ce nombre est utilisé à tort.

$2 π$ fois cette grandeur est appelé paramètre de Hall.
