O069400100010 COMMENT -By authors. The accelerated lithium beam was directedO069400100011 normally to the target surface with the aluminum layer O069400100012 facing the ion beam. With this configuration it was O069400100013 not necessary to put any stopper foil in front of the O069400100014 charged particle detectors, as the H peak was well O069400100015 separated from the C and N recoils. O069400100016 REL-REF (R,,W.D.WARTERS+,J,PR,91,917,1953) The data for elasticO069400100017 scattering of protons by lithium were used for O069400100018 comparing.

The statistical errors of the count rates of peak O069400100039 areas for backscattered and recoiled particles, O069400100040 2. Error of normalization O069400100041 3. The errors of the detector angular settings.
