Excitation and decay of projectilelike fragments formed in dissipative peripheral collisions at intermediate energies

Projectilelike fragments (PLF, $15<~Z<~46)$ formed in peripheral and midperipheral collisions of ${}^{114}\mathrm{Cd}$ projectiles with ${}^{92}\mathrm{Mo}$ nuclei at $E/A=50\mathrm{}\mathrm{MeV}$ have been detected at very forward angles, $2.1°<~{\theta }_{\mathrm{lab}}<~4.2°.$ Calorimetric analysis of the charged particles observed in coincidence with the PLF reveals that the excitation of the primary PLF is strongly related to its velocity damping. Furthermore, for a given $V_{\mathrm{PLF}*},$ its excitation is not related to its size, $Z_{\mathrm{PLF}*}.$ For the largest velocity damping, the excitation energy attained is large, approximately commensurate with a system at the limiting temperature.
