3He(e,e′pp) and 3He(e,e′pn) reactions at AmPS and MAMI

This paper reports on measurements of the ³He(e,e′pp) reaction measured at AmPS and the ³He(e,e′pn) reaction measured at MAMI. The measurements were performed in similar kinematics to allow a comparison to be made between the cross sections of the two reactions. Results are shown for both reactions together with a comparison for the ³He(e,e′pp) data with continuum Faddeev calculations.     

Die Kristallstrukturen der Triarylzinkate [Mg2Br3(THF)6][ZnPh3] und [MgBr(THF)5][ZnMes3]

Crystal Structures of the Triarylzincates [Mg₂Br₃(THF)₆][ZnPh₃] and [MgBr(THF)₅][ZnMes₃] The title compounds were obtained from reactions of the phosphoraneiminato complex [ZnBr(NPMe₃)]₄ with excess Grignard reagents RMgBr (R = C₆H₅, 2,4,6-(CH₃)₃–C₆H₂) in THF solution. According to X-ray structure determinations the [ZnR₃]^– ions contain zinc atoms which are coordinated in a planar fashion with Zn–C distances of 200.7 pm (R = Ph) and 203.4 pm (R = Mes) in average.
