Figure 8
Free-electron fraction, p, and (1 − p)2 as a function of the electric field calculated using equations (14) and (15). The solid and broken lines indicate the results for d = 4.2 and 8.4 mm. The factor of (1 − p)2 is the ratio of K in equation (6) to that in equation (13), i.e. the rate of change of K. |
