Über die Theorie der molekularen Lichtzerstreuung in Kristallen (klassische Theorie)
Die Lichtzerstreuung in einem Kristall wird als Beugung an den elastischen Schwingungen des Kristalls gedeutet. Bei der Streuung ändert sich die Frequenz des Lichtes μm ω0 (ω0=die Frequenz der für den betrachtete...

Partial-wave analysis of the ωπ0 system at high masses
Recent results on ωπ0 partial-wave analysis from the GAMS Collaboration are presented. A partial-wave analysis of the 38 GeV/c π-p charge exchange data confirmed the existence of theρ(2200) radial-orbital excitat...
