Electron precipitation induced by oblique whistler waves is investigated using a new test particle simulation code based on gyro-averaged equations of motion. Results indicate that highly oblique waves can efficiently pitch angle scatter suprathermal electrons (10--100 eV). At L=3, for example, in a single encounter with a wave with power density S~8 pW/m2 and propagating at &psgr;=60¿ with respect to the Earth magnetic field Bo, average pitch angle scattering of 100 eV electrons is ~0.1¿. In comparison, the average scattering of energetic (100 keV) electrons by a parallel propagating wave with the same S is ~0.01¿. Estimates indicate that the precipitated electron energy fluxes resulting from the interaction of ~100 eV electrons with oblique waves can be up to 30 times larger than that due to the precipitation of 100 keV electrons by parallel propagating waves. ¿ American Geophysical Union 1992 |
