Study of Recoil Properties of Target Residues From the Interaction of Copper With 20─46MeV/u 12C Ions

  • By using off- line γ-ray spectroscopy in conjunction with thick target-thick catcher foil techniques,the mean forward recoil ranges have been measured for the residues produced from interaction of copper with 20—46MeV/u 12Cions.From these data,linear momentum transfer for central collisions has been extracted. The linear momentum transfer per incident nucleon attains a maximum value of 155MeV/c at approximately 27.5MeV/u.The maximum excitation energy of the composite system is found to be 2.5MeV/u.

Abstract: By using off- line γ-ray spectroscopy in conjunction with thick target-thick catcher foil techniques,the mean forward recoil ranges have been measured for the residues produced from interaction of copper with 20—46MeV/u 12Cions.From these data,linear momentum transfer for central collisions has been extracted. The linear momentum transfer per incident nucleon attains a maximum value of 155MeV/c at approximately 27.5MeV/u.The maximum excitation energy of the composite system is found to be 2.5MeV/u.
