An atomic beam is designed to function with
(a) Cadmium,
(b) Mercury. The source is an oven maintained at 380 K, there being a small slit of dimensions 1.0 cm x 1.0 x 10-3 cm. The vapour pressure of cadmium is 0.13 Pa and that of mercury is 12 Pa at this temperature. What is the atomic current (the number of atoms per unit time) in the beams?
