Abstract
A direct method for measuring the desorption time constant of flash-desorbed He4 films (1 monolayer), adsorbed on Nichrome or Constantan heaters, is described. A time constant is found which behaves as =0exp[ETs], where Ts is the heater temperature. The value for the characteristic lifetime 0 is 10-9-10-10 sec, orders of magnitude shorter than that previously reported. The measured energy parameter E was found to be 23 of the chemical potential.
