Pascal Prize of the Académie des Sciences
Author of:
- Quantum Chemistry (with R. Daudel and C. Moser), Interscience, 1959.
- About 200 scientific papers
Important Contributions:
- Use of Brillouin theorem to calculate self-consistent field orbitals of close and open shell systems.
- Determination of electron spin resonance spectra of polyoriented radical and triplet state species.
- Study of sequential versus non-sequential behaviour, and of recurrences, in the decay of molecular resonances.
- Methods based on the integration of coupled equations for the study of photodissociation and Raman processes.
- Resonance quantization from an integration of coupled equations with Siegert boundary conditions. Use of optical potentials, of complex rotation and of Padé approximants.
- Intense-field photofragmentation dynamics combining Floquet theory and complex rotation.
- Effect of time-dependent perturbations on resonant tunneling.
