Main research contributions
1. Researches in Nuclear Physics
1.a Centre de recherches nucléaires in Strasbourg
Experimental studies of the nuclear structure of nuclei in the 1s, 2p, et 1f7/2 shells (determination of the spin of nuclear levels and their lifetime) were performed by gamma spectroscopy. A theoretical interpretation was performed using the shell or collective models, showing the important role of the nucleus shape (spherical or oblate or prolate) on the nuclear properties (see the list of references before 1979).
1.b Laboratory CIMAP (ex-CIRIL) in Caen
Lifetime measurements are always a striking test of any models. My competences, in nuclear physics and in channeling of ions in crystals, were used to determine the mean lifetime, in the attosecond range, of compound nucleus resulting from the fission of uranium nucleus [see ref. Phys. Rev. Lett. 82 (1999) 5012].
2. Material for solar energy (PHASE Laboratory (presently INeSS) in Strasbourg)
2.a Determination of components in amorphous silicon : Role of hydrogen.
Using the nuclear characterizations to determine the relative composition of impurities in amorphous silicon, the efficiency of doping was quantified : The doping impurities are passivated by the hydrogen and only 1% of the impurities are electrically active [see ref. Appl. Phys. Lett. 39 (1981) 154].
2.b Laser-matter interaction
Amorphous silicon deposited on crystalline silicon can be recrystallised by an irradiation with ns laser pulse. The time and depth of melting the silicon was measured and compared successfully to a model that describes the laser energy deposition in the silicon and the consecutive transient thermal process that allows the epitaxial recrystalisation of the induced liquid phase [see ref. Appl. phys. 19 (1979) 313].
