Description

High-resolution inelastic electron scattering (FWHM approximately equal to 33 keV) with 50 MeV and 63.5 MeV electrons on 208Pb has been used to study magnetic excitations between Esub(x) = 6 MeV and 8 MeV. Angular distributions were analyzed in terms of the DWBA with RPA wave functions. Eight Isup(π) = 2- states carrying a total strength ΣB(M2) = 8500 μ2sub(K) fm2 have been found. The strong fragmentation is in qualitative agreement with theoretical predictions. (orig.)

Abstract (German)

Die hochaufgeloeste inelastische Streuung (FWHM ungefaehr gleich 33 keV) von 50 MeV und 63.5 MeV Elektronen an 208Pb wurde zur Untersuchung magnetischer Anregungen zwischen Esub(x) = 6 MeV und 8 MeV verwendet. Im Rahmen der DWBA wurden die Winkelverteilungen mit RPA-Wellenfunktionen interpretiert. Acht Isup(π) = 2--Zustaende mit einer Gesamtstaerke von ΣB(M2) = 8500 μ2sub(K) fm2 wurden aufgefunden. Die starke Fragmentation stimmt qualitativ mit theoretischen Vorhersagen ueberein. (orig.)
