We have developed an apparatus to polarize 3He gas (at a few torrs pressure) by optical pumping from a 4He light source and to measure the evolution of the magnetic moment for relaxation studies. The magnetic moment is measured by applying a pulse of radio ...
A general result is proven concerning time-variant displacement equations with positive solutions in a general operatorial setting. It is then shown that the solutions of several completion problems, recently considered in connection with classical interpo ...

The effects of thermal trapped particles on the internal kink mode are studied using drift kinetic theory. For equal electron and ion temperatures, the trapped particles increase the marginal poloidal beta at q=1 substantially. For unequal temperatures, dr ...
The parallel velocity distribution function of the weakly relativistic electron beam of a quasi-optical gyrotron has been determined by measuring the Doppler-shifted Electron Cyclotron Emission (ECE) at an angle theta=15 degrees with respect to the externa ...
We do not intend to give here a background knowledge on vacuum field Rabi splitting. The reader should refer to J.M. Raimond, T. Norris, H. Yokoyama and D.S. Citrin lecture notes. For the sake of completeness we simply remind the reader that the cavity qua ...
The paper describes measurements of the sawtooth instability in JET, in which the instability wave function is shown to extend to the edge where it is measured using magnetic coils. The numerous magnetic probes in JET allow the time evolution of the (n = 0 ...
The dipole moment of NO(B (2) Pi) was determined for the first time by high resolution laser-induced fluorescence molecular beam spectroscopy. Specific values obtained areas follows: mu(upsilon' = 3) = 0.293(3) D, mu(upsilon' = 4) = 0.276(9) D and mu(upsil ...
Two-dimensional high-resolution solid-state NMR has been used to study C-13-enriched wood. Wood is a complex material containing three major polymers: cellulose, hemicelluloses and lignin. The use of an enriched C-13-compound allows the observation of intr ...
In the frame of the RD26 collaboration at CERN we have built and tested several prototypes of fast-RICH detectors suitable for the construction of large systems. The detectors used a solid photocathode consisting of a 500 nm CsI layer evaporated on a conve ...
The anal. of 2-dimensional NOESY spectra can be misleading if spin diffusion effects are not properly taken into account. An approach consisting in suppressing spin diffusion by selective inversion of the spins undergoing the Overhauser effect, known as QU ...
