Proton resonance reactions using heavy ion beams has been studied with
an 17O beam on polypropylene and ZrH targets.
Resonances were studied
at bombarding energies of 14 and 20 MeV of 17O.
Low beam intensities
of the order of 10^7 ions/s have been used to avoid hydrogen loss due to
damage by the heavy ion beams. The targets are thick enough to stop the
heavy ion beams, but thin enough to let the recoil light particles
escape the target. A large solid angle (180 msr) micro strip detector
was used to register protons and alphas and high quality excitation
functions can be obtained in a single exposure of about 30 minutes.
Here is a typical excitation function obtained in our recent experiment.
This technique can be very valuable for studies with radioactive beams
and will be tested with 17F beams of HRIBF.
