Abstract

Total cross sections for 88-Mev gamma-rays have been measured in 6 elements by absorption methods to a statistical accuracy of about 1.5 percent. The results expressed in

{cm}^{2}

/gram are 0.0107, 0.0252, 0.0471, 0.0665, 0.0909, and 0.0973 for the elements Be, Al, Cu, Sn, Pb, and U, respectively. Values appear generally lower than predictions of existing theory by a factor proportional to
