ELASTIC SCATTERING OF PHOTONS BY TANTALUM

Results are described of a measurement of the differential cross section at 120 for the elastic scattering of photons by tantalum. The experimental cross section as a function of energy is in better agreement with the result calculated from the tengor expression than that obtained assuming a scalar polarizability. This tends to confirm the spatial correlation of the dipole polarizability for a deformed nucleus. (T.B.A.)
