Analysis of radioactive beam shift on target using 11Li scattering from Ag and H2 targets

Abstract

The halo nucleus [superscript 11]Li was explored through elastic and inelastic scattering off protons at the TRIUMF facility in Vancouver using the IRIS facility. IRIS pioneers in using thin windowless solid hydrogen target to measure reactions with radioactive ion beams at low energy. To examine the excitation spectrum of [superscript 11]Li, the excitation energy was found from the scattering angle and energy. It is important to evaluate the effect of beam position relative to the center of the solid hydrogen target. A shift in the beam can lead to energy differences of ~ 0.5% to 1% depending on the incident angle on the detector. The focus of this thesis is to investigate the beam position on the target relative to the detectors.
