This thesis describes the experimental work done on the 2.14 MeV level of boron 11. The purposes of this investigation were to confirm the existence of the 2.14 MeV level and to find experimental conditions suitable for measuring its width and lifetime. It was hoped that the width and lifetime could be measured more accurately than previously. The work consists of a scattering experiment in which a 6 MeV medical linear electron accelerator was used to produce X-rays for the photo-excitation. The resonantly scattered photons from the boron 11 at an angle of 120 degrees to the incident beam were studied. A tremendous amount of difficulty was encountered in the form of background radiation due to other forms of scattering throughout the chamber. Methods for reducing the background are described at various points in the thesis.
