Abstract

Fragment emission mechanisms have been studied in ¹²C on ¹²C and ¹³C on ¹²C reactions at same excitation energy. The inclusive energy distributions of the complex fragments (3≤ Z ≤ 5) emitted from the composite system have been measured in the angular range 14° to 36°. The present experiments have been performed with the motivation to study the isotopic dependence of fragment yields in these two reactions. From the preliminary analysis, it has been observed that fragments are emitted from a completely equilibrated and long lived composite system for both ¹²C + ¹²C and ¹³C + ¹²C reactions. It has also been observed that the emission of neutron-rich fragments are more in ¹³C + ¹²C compared to ¹²C + ¹²C reaction.
