Radiochemical activation techniques were used to study the behavior of projectile fragments formed in the interaction of 44 GeV C-12 ions within thick Cu targets. After a short review of the results obtained hitherto with this Cu-target technique, the interaction of 44 GeV C-12 with several copper target configurations yielding the deep spallation product Na-24 is described. Energetic fragments which are emitted into the laboratory angles 10-degrees less-than-or-equal-to theta less-than-or-equal-to 45-degrees appear to produce more Na-24 (up to nearly one order of magnitude) than calculated with a phenomenological model and an intranuclear cascade model. This enhanced production of Na-24 by wide-angle secondaries is only observed for 44 GeV C-12 on copper, but not for 25 GeV C-12 on copper. Some normalization experiments with 4 GeV He-4 and 2.6 GeV p are described.
