Experiments have been performed with the moderately intense electron-beam pulses (8 kA/cm{sup 2} peak) at the Los Alamos National Laboratory pulsed high-energy radiographic machine emitting x-rays (PHERMEX) facility and with the much weaker beam at the Naval Research Laboratory linac, to measure energy absorption in Al, Ti, and W targets. The energy spectra at the two facilities were similar, with an average energy of about 26 MeV. A calorimetric method was used to measure the deposited energy. The experimental results are compared to each other and to Monte Carlo integrated tiger'' system (ITS) code calculations. Calorimeters consisting of two and four sections were used. The linac data were in good agreement with single-electron code calculations. Evidence for collective effects appears as a redistribution of the absorbed energy in the PHERMEX data, although the beam intensity is very much lower than in previous investigations of this effect.
