✦ Synopsis

Photofragmentation of benzene cluster ions, (C6H6) + with n = 5-8, is studied in a wide photon energy range of 0.5-3.0 eV. Apparent evaporation energies for n = 5-8 are determined to be 0.55-0.52 eV. These are approximately 0.2 eV larger than the binding energies for one neutral monomer to the cluster ions. The average translational energies of 50-75 meV for ejected neutral monomers are obtained in the photon energy range of 1.1-2.0 eV. The remainders of nearly 0.2 eV cannot be explained only in terms of the translational energies of the photofragments. This result indicates that a part of the imparted energy is partitioned into photofragments as internal energies.
