Properties of projectile fragments produced in peripheral and midperipheral collisions in the reaction [sup 40]Ca + [sup nat]Cu at 35 MeV/nucleon were investigated using the AMPHORA multidetector. A reconstruction of the primary projectilelike fragments enabled simultaneous determination of their excitation energy and angular momentum. These quantities are in good agreement with predictions of simple macroscopic and microscopic collision models. Partition of excitation energy between primary projectile and targetlike fragments is discussed. The multiplicity and charge distributions of the primary projectilelike fragment deexcitation products are fairly well reproduced by a statistical binary-decay model.
