Belgrade, Serbia and Montenegro The backbone of the DNA molecule may be seen as a series of tetrahydrofuran (THF) molecules connected by phosphate bonds to which the bases are attached. Qualitative estimation of effects linked to chemical and structural changes of cellular DNA connected with radiation damage is performed by electron interactions with THF (C4H8O) sugar-like analogue molecule in gas phase. We report results for elastic scattering of electrons as a function of angle and electron impact energies. The absolute elastic differential cross section (DCS) as a function of scattering angle (10°-110°) is presented at impact electron energy range from 10 to 300 eV. Experimental set-ups used in the experiment are two electron spectrometers designed for lower and higher energy ranges, the first being of hemispherical electrostatic type and the other of double cylindrical mirror type.
