An angular method of identifying diffractive excitation (DE) events for interactions of a hadron beam in nuclear emulsion is applied to identifying DE events in interactions of heavy ions beams. The apparent'' mean free paths (MFP) of DE processes for {sup 16}O ({sup 28}Si) beams are 1.00{plus minus}0.12, 2.4{sub {minus}0.7}{sup +1.6}, and 2.2{plus minus}0.4 (1.5{plus minus}0.2) m, respectively, at 200, 60, and 14.6 GeV/nucleon, which corresponds to 20--10% of the MFP for total inelastic interactions. Distinctive features of diffractively excited nuclei are discussed.
