X-ray and electron-energy-loss data are in good agreement. Present theories of atoms and of solids, including some many-electron theories, do not explain these features.

Electron -energy-loss spectra at a variety of momentum transfers have been obtained in the region of the 4d excitation in tellurium. This region of the spectrum exhibits strong collective effects. Comparison of the results of the calculation with the experimental results reveals a discrepancy in the energy of the 4d excitation at large momentum transfer (short wavelength). Comparison of the results of the calculation with other experimental work on the noble gases reveals other discrepancies and allows the identification of higher order multipole excitations.

A single scattering optical potential is used with nuclear and nucleon form factors as determined elsewhere and the ..pi..N scattering amplitude expressed in terms of phase parameters. It is found that several of the N phase parameter sets can be

Good agreement is obtained with available data near 1 GeV and choices are made for the nuclear and nucleon charge form factors and among the phase parameter sets at this energy.
