Strong Pitch Angle Scattering and the Kennel-Petschek Limit

Strong Pitch Angle Scattering and the Kennel-Petschek Limit. D. N. Baker LASP – CU/Boulder. The Kennel-Petschek Limit. In 1966 paper, for electrons:. E R = E 0 W/w (1 - w/W) 2 E 0 = B 2 /8p n J*(> E R )= [(1-E 0 /E R )/(A-E 0 /E R )] x 10 10 B lnG/ l. (cm -2 s -1 ).
