O071700100010 (20000427A) DATE is corrected O071700100011 SAMPLE The target,a Uranium filament with a diameter of 0.13mmO071700100012 was adjusted by optical means at the centre of a O071700100013 cylinder (R=65 mm). The target can be moved in two O071700100014 perpendicular directions at the two points where it O071700100015 was fastened to the cylinder. O071700100016 The fragments emitted from the target were collected inO071700100017 TEN polyethylene foils mounted around the cylinder. O071700100018 The thickness of the catcher foils was 9.2 mg/cm**2, O071700100019 that is a few times the maximum range of fission O071700100020 fragments. By adding a second foil behind each catcher O071700100021 foil, it was checked that the only activity produced O071700100022 in the plastic foils is C-11.

All activities followed for at least 20 hours.O071700100027 C-11 formed was allowed to decay before the foils were O071700100028 counted. O071700100029 CORRECTION Correction on Centre-Of-Mass System motion were O071700100030 included. It is assumed that the preferred direction O071700100031 of the Centre-Of-Mass motion is in the direction of theO071700100032 incident protons and further that the angular O071700100033 distribution is symmetric about 90 degrees in the O071700100034 Centre-Of-Mass System.
