Experiments on Quantum and Thermal Desorption from 4He Films (1985)
Goodstein, D. L., Maboudian, R., Scaramuzzi, F., Sinvani, M., Vidali, G.
Desorption of He atoms from thin films may be resolved experimentally into quantum and thermal components. We show that quantum desorption becomes the dominant part of the signal in submonolayer...
Desorption of helium atoms from thin films (1984)
Sinvani, M., Goodstein, D. L., Cole, M. W., Taborek, P.
Investigation is made of the desorption of He atoms from thin films. Three different experimental geometries are used to study the dependence on substrate material, film temperature, and duration of...
Sticking probability of 4He on solid surfaces at low temperature (1983)
Sinvani, M., Cole, M. W., Goodstein, D. L.

Direct measurement of desorption kinetics of 4He at low temperatures (1982)
Sinvani, M., Taborek, P., Goodstein, D.
A direct method for measuring the desorption time constant of flash-desorbed 4He films (≲ 1 monolayer), adsorbed on Nichrome or Constantan heaters, is described. A time constant τ is found which...
FILM THICKNESS DEPENDENCE OF HEAT TRANSMISSION INTO HELIUM (1981)
Taborek, P., Sinvani, M., Weimer, M., Goodstein, D.
A heater is pulsed at the interface between a sapphire crystal and an adsorbed 4He film. For short pulses, the amount of heat absorbed by the film saturates when the film thickness reaches a few...
POLARIZATION DEPENDENCE OF PHONON INDUCED DESORPTION OF He ATOMS AT LOW TEMPERATURES (1981)
Taborek, P., Sinvani, M., Weimer, M., Goodstein, D.
We directly observe the desorption of He atoms from a thin film on the surface of a solid by both longitudinal and transverse ballistic phonons. Ballistic propagation of the He atoms, sound in the...
TIME CONSTANT FOR PHONON INDUCED DESORPTION OF HELIUM (1981)
Taborek, P., Sinvani, M., Weimer, M., Goodstein, D.
We have made direct measurements of the time constant for thermal desorption of thin helium films as a function of substrate temperature and film binding energy. We find that the attempt frequency...

Zair, E., Sinvani, M., Levy, B., Greenfield, A.
The existence is reported of remanent superconductivity in the normal phase of Al well above Tc. This remanent superconductivity is shown to explain the different experimental findings in the...
