A parameter reflecting the laser-power efficiency of the proton acceleration is used for comparison of the observed maximum proton energy with data from other experiments. The number of protons and deuterons constituting the backward and forward jets is estimated. Values of maximum proton energies and electron temperatures indicate that the laser intensity should reach a relativistic level through the laser beam self-focusing. The occurrence of electron bunches in front of the irradiated target surface was identified by time resolved femtosecond interferometry. Energy distribution functions of electrons emitted in the both backward and forward directions are analysed and compared.
