    Notes: [Auszug] Conversi, Pancini and Piccioni1, and others2, observed decay electrons from positive mesons coming to rest in solids of either light or heavy elements. For negative mesons, however, decay electrons were found in light elements only; for heavy elements it is ...

    Notes: [Auszug] Van Vleck and Weisskopf1, in an interesting paper, have shown that the well-known Lorentz formula for the shape of a spectral line is incorrect except at frequencies close to the resonance frequency. Since this formula has been considered to be correct for a great number of ...

    Notes: [Auszug] A VERY drastic change in the present conception of the interaction of mesons with atomic nuclei was suggested by Fermi, Teller and Weisskopf1 as a result of the experiments by Conversi, Pancini and Piccioni2, who observed the behaviour of positive and of negative ...

    Notes: [Auszug] IN considering tMe behaviour of electrons in crystalline solids, a irfrell-known theorem by F. Bloch is of great importance. According to this theorem, electrons in a/perfectly periodic lattice move freely without b uig scattered. This does not mean, however hat all electrons contribute to the ...
