A method to measure transient heat transfer to liquid helium from a thin metal film heater under the condition of pulsed heating during r < 400 ns is proposed. The experimental equipment used for the measurements is described. The method is based on the comparison of heat pulses transfered from the

We report the results of photographic studies which show that light induces the nucleation of vapour bubbles in superheated liquid helium I. We believe that these bubbles are associated with the cooling that we have previously observed to result from a flash of visible light applied to the surface o
