First International Conference On Laboratory Research For Planetary Atmospheres

Organized in honor of K T Hecht, Professor of Physics at the University of Michigan, for his frontier research in group theory and nuclear physics, this symposium features papers by principal researchers who have contributed to the development and use of algebraic methods in nuclear physics. The symposium aims to make a critical assessment of what has been accomplished since the seminal work of J P Elliott on the SU(3) model, and to identify significant challenges and opportunities that lie in the future. Topics include the SU(3) model and its noncompact Sp(3, R) extension, boson and fermion dynamical symmetry schemes, pseudo-spin and superdeformation, cluster model configurations and calculations, recent advances in vector coherent state theories, quark models for subnucleon degrees of freedom in nuclei, and more.

The abstracts deal with the nature of cometary ices, cryogenic handling and sampling equipment, origin and composition of samples, and spectroscopic, thermal and chemical processing methods of cometary nuclei. Laboratory simulation experimental results on dust samples are reported. Some results obtained from Halley's comet are also included. Microanalytic techniques for examining trace elements of cometary particles, synchrotron x ray fluorescence and instrument neutron activation analysis (INAA), are presented.
