Partial wave analysis together with the qualitative examination of hybridization has been performed for two ordered intermetallic alloys with CsCl structure, FeV, and CoTi. The results resemble those obtained previously for FeTi, although important deviations are present as well. The stabilization of the ordered phase is again due to ionic effects. Qualitative arguments are suggested to explain the small stability of the CsCl phase of FeV and some differences in the FeTi and CoTi phase diagrams.
Arguments based on unitarity and analyticity suggest that there is no 1++ partial wave in a process such as e+e− 1 γγ 1 μ+μ−. This note demonstrates that, in fact, such a partial wave does exist. Reasons for the apparent breakdown of traditional arguments are briefly discussed.
