O135800100010 COMMENT -By authors. A nondestructive method for carbon O135800100011 determination in layers of 3-10-mum thickness is O135800100012 considered. The method is based on using the C-12(d,n) O135800100013 nuclear reaction with simultaneous account of surface O135800100014 contamination by means of the C-12(d,p)C-13 competitiveO135800100015 reaction. O135800100016 SAMPLE The thin target containing 15-mug/cm**2 of carbon was O135800100017 used. The thin target was made by means of C-12 ion O135800100018 implantation into high purity molybdenum backing. O135800100019 ADD-RES 1.
