24Mg (α, α1γ) angular correlation at Esub(α) = 104 MeV for the investigation of the reaction mechanism of the inelastic α-scattering and the deformation of 24Mg
Description
The particle γ angular correlation of the reaction 24Mg (α, α1γ)24Mg was studied at the isochron cyclotron of the Karlsruhe nuclear research centre at an injection energy of 104 MeV. The double differential cross section was measured for 126 angle pours (PHIγ, PHIα) in the reaction plane. The multidetector arrangement used consisted of 4 Si(Li) detectors to detect the scattered α particles and 2 Ge(Li) detectors for the detection of the γ quanta. The data were analyzed with the coupled-channel method using the inclastic symmetric rotor model. Apart from the usual phenomenological optical potential (macroscopic model), a simpler folding model (semimicroscopic model) was also used. (orig./WL)

Am Isochron-Zyklotron des Kernforschungszentrums Karlsruhe wurde die Teilchen-γ-Winkelkorrelation der Reaktion 24Mg(α, α1γ)24Mg bei einer Einschussenergie von 104 MeV untersucht. Der doppeltdifferentielle Wirkungsquerschnitt wurde fuer 126 Winkelpaare (PHIγ, PHIα) in der Reaktionsebene gemessen. Die hierzu verwendete Mehrdetektoranordnung bestand aus 4 Si(Li)-Detektoren zum Nachweis der gestreuten α-Teilchen und 2 Ge(Li)-Detektoren zum Nachweis der γ-Quanten. Die Analyse der Daten erfolgte mit der Methode der gekoppelten Kanaele unter Verwendung des Modells des starren symmetrischen Rotators. Dabei wurde sowohl der uebliche Weg ueber ein phaenomenologisches optisches Potential (makroskopisches Modell) beschritten als auch ein einfaches Faltungsmodell (semimikroskopisches Modell) verwendet.
