Response to the following problem:
An oven contains cadmium vapor at a pressure of 2.28 Pa and at a temperature of 550 K. In one wall of the oven there is a slit with a width of 10-5 m and a length of 10-2 m. On the other side of the wall is a very high vacuum. If one assumes that all the atoms arriving at the slit pass through, what is the atomic beam current?
