M1 strength for the population of low lying states in ¹¹B — •V. M. Hannen — KVI, Groningen, NL

We will report on the (p^→, p′) reaction on an ¹¹B target using a 150 MeV polarized proton beam from the AGOR cyclotron. The scattered particles were momentum analyzed with Big-Bite Spectrometer and detected in the EUROSUPERNOVA Focal-Plane Detection and Polarimeter system. Our objective is to extract cross sections and analyzing powers for states up to an excitation energies of 10 MeV. Typical energy resolution achieved was 100 keV, data were taken at angular settings between 5^∘ and 28^∘. The measured beam polarisation was about 75 % for both the spin-up and spin-down setting of the polarized ion source.
