Issues

The study of how nuclei absorb and emit energy has progressed dramatically in the last few decades and has effects in fields as diverse as astrophysics and medical diagnostics.

The numerous mesons and baryons are remarkably well explained as states of simple quark “atoms” that obey the same principles as ordinary atoms.

Using modern experimental and theoretical techniques, an old field has come alive, motivated by applications in a wide variety of areas, ranging from measurement in fundamental physics to elemental analysis in astrophysics.

Analyzing the energies of x‐ray and uv photoexcited electrons, of Auger electrons and of inelastically scattered electrons, among others, has provided much new and practical information about surfaces.
