-27, 1982. The motivation for the conference was, in a large part due to the recent development of new variable energy accelerators which produce high quality beams of electrons, protons, and pions that are providing the first precise information on spin excitations in nuclei over a large range of s

Nucleus as a Chiral Filter: The Role of the Δ (1232)dler-Weisberger relation, it is argued that the observed ~ 50% quenching of the Gamow-Teller strength reflects the possibility that the Gamow-Teller operator sees the quarks inside the bag, blind to the Goldstone vacuum outside. Some implications on chiral phase transitions are also discussed.

Lorentz-Lorenz Quenching for the Gamow-Teller Sum Rulese σ τ. strength which is the quantity accessible through (p,n) reactions and Pauli blocking rapidly suppresses the T. branch as (N-Z) increases. Thus, if one assumes that no part of the strength has escaped detection, a reduction such as that observed in a wide range of nuclei is strongly suggestive of the intervention of new degrees of freedom.

Implications of Density Dependence in the Effective Interaction for the Excitation of Spin Modestering. We shall concentrate on the sensitivity of nucleon inelastic scattering and charge exchange to the properties of the free two-nucleon interaction and the modifications due to the nuclear density.

Opening Remarks: Basic Quark Considerationseller strength or why is it missing? Our first speaker may not be able to tell us where it has gone, but he can certainly tell us where the idea came from. It is my pleasure to introduce Dr. Edward Teller.

The Search for M1 Strengthmining M1 strength is mainly restricted to nuclei with A<100. For nuclei below A≃40, the total measured M1 strength is in good accord with detailed shell model estimates, however, heavier nuclei show a strength deficit in comparison with model predictions.

Observation of M1 Strength in Medium-Heavy Nuclei via the (p,p′) Reactiontent with an orbital angular momentum transfer of zero. The excitation energy, angular distribution and strength of the resonance suggest that it is the giant M1 resonance. In the nickel isotopes, and in .V, both the T. and T.+1 components of the resonance are observed.
