The Vapor Pressure of Americium

摘要

The vapor pressure of americium from a dilute solution in plutonium has been measured by a modification of the Knudsen effusion method. The resulting vapor pressure for pure americium in the temperature range 1450°K to 1820°K is given by the equation log10pmm=7.02—(11,300)/T. The vapor pressures are probably accurate to a factor of two or three. Relative values are much more precise.
