Measurements of the electrodisintegration cross section /sup 238/U(e,e',n)/sup 237/U in the energy region 6--25 MeV are presented. A virtual photon analysis of experimental data shows that neutron emission occurs only through E1 absorption. Our data establish an upper limit to the strength of E2 transitions, which is only 0.25% of the E1 transitions. Existing data on the decay channels of the isoscalar giant quadrupole resonance in /sup 238/U are compared with available data on E2 absorption by this nucleus. A discussion of available experimental data indicating a selectivity of decay modes on the spin and parity of the excited resonance is presented. The sensitivity of electrodisintegration cross sections to the existence of quadrupole components is assessed.
