✦ Synopsis
Let us draw a cylinder bounding ds, penetrating the solid, and emerging at ds', the axis of the cylinder being parallel to that of dw. Then, if 6 is the coefficient of absorption of the corpuscles in the solid, the number emerging from ds', per FE. I.
Verfical
second, after having approached it within a solid angle equal to dw is Ae-@ cos a'dwds' ,
where (Y' is the angle between the normal to ds' and the axis, of dw, and I is the length of path between ds and ds'. Now if da is the cross section area of the cylinder, da = cos cxds = cos cr'ds', so that the difference between (I) and (3) gives
If 0' is small, as it would have to be if the foregoing experiments were to be consistent with an influx of corpuscles sufficient to account for the maintenance of the earth's charge, we may expand the exponential, and write (4) as Afi'ldwda.
