Synopsis We present measured absolute double differential cross section (DDCS) of electron emission from fluorene (C 13 H 10 ) molecule upon 3.5 MeV/u Si 8+ ion impact. We have compared the energy and angular distributions of the DDCS with CB1 (Ist Born with correct boundary conditions) calculations. The e-DDCS shows an indication of collective excitation peak in low energy part of the spectrum at a few backward angles. The shape of the distribution has also been compared with that for a smaller molecule i.e. CH 4 .
