Abstract
We present the results of an absolute measurement of the photoabsorpti on cross section on Li, C, Al, Cu, Sn, and Pb between 300-1 200 MeV. I n the DELTA region our results confirm that the strength is conserved, while in the higher resonances region they show a 7-15% damping and a possible mass-number dependence of the photoabsorption cross section.
