Intermediate spin, Schr\"odinger cat states and nano-magnets
Quantum tunneling of nano-magnets finds a natural description in terms of
intermediate spin. Periodic magnetic effects correspond to a change of flux by
the flux quantum . Schr\"odinger cat states with different
superpositions of the applied magnetic field occur. The molecular magnet
Fe is discussed and oscillations are predicted for Mn.Comment: 4 pages 4 figure
Associated Charmonium Production in p-pbar Annihilation
In this paper we summarize our recent results for low energy associated
charmonium production cross sections, using 1) crossing symmetry, and 2) an
explicit hadronic model. These predictions are of relevance to the planned
charmonium and charmonium hybrid production experiment PANDA at GSI.Comment: 5 pages, 5 figures. Contribution to the Second Meeting of the APS
