Angular distribution of the $^{4}$He($^{3}$He,$\gamma )$$^{7}$Be reaction

The $^{4}$He($^{3}$He,$\gamma )^{7}$Be is key reaction in high energy solar neutrino production. A measurement of the gamma-ray angular distribution provides insight into the reaction mechanism and allows better extrapolation of the cross section to low energies. A gas cell experiment has been designed and built to study the angular distribution. This work reports on the design and construction of the gas cell and the gas handling system as well as energy loss measurements in the cell. The cell was designed to reduce the background due to beam interaction with the entrance and exit foils. The detector geometry was studied and calculated to optimize response and efficiency. Results of preliminary gamma ray measurements with a $^{3}$He beam will be presented.
