Abstract Cross sections and analyzing powers for the 11B(p (arrow),p (arrow)) reaction have been measured using a 150-MeV polarized proton beam from the AGOR cyclotron at KVI. For the stronger inelastic transitions, also spin-flip probabilities have been extracted. To predict cross sections and spin observables a microscopic (coordinate space) model of elastic scattering has been used, whereas for inelastic scattering calculations were performed in the distorted-wave approximation. In the model calculations a medium-modified two-nucleon effective interaction was used and nuclear structure information was obtained from shell-model calculations in a complete (0 + 2)(h with stroke) (omega) model space for parity-conserving transitions and a 1 (h with stroke) (omega) shell-model description in the case of parity-changing transitions. With the help of these model calculations, spin-isovector parts of the M 1 strengths for the negative-parity states at excitation energies of 2.125 MeV (Jp=1/2-), 4.445 MeV (Jp = 5/2-), 5.020 MeV (Jp=3/2-), and 8.920 MeV (Jp=5/2-) have been extracted and compared to known Gamow-Teller strengths for the analog transitions to 11C.
