YIELDS AND ANGULAR DISTRIBUTIONS OF PROTONS FROM F$sup 19$ (d,p)F$sup 20$ AND F$sup 19$ (d,p)$sup 20$ *
The reactions F/sup 19/(d,p)F/sup 20/ and F/sup 19/(d,p)/sup 20/ were studied with deuteron bombarding energy of 1.3 to 2.0 Mev, Angular distributions of protons leaving F/sup 20/ in 0.65 Mev excited state show a pronounced peak at about 60 over the entire deuteron energy range. On the other hand, those leaving F/sup 20/ in the ground state vary with the deuteron bombarding energy and most of them show no peak in the forward dircction and a large peak in the backward direction. The absolute yields of the reactions were measured at theta /sub cm/= 54 and theta /sub cm/ = 104 as functions of the bombarding energy. A marked difference in the energy dependence of the yields for the two reactions is noted. The yield for the reaction F/sup 19/(d,p)F/sup 20/ at theta /sub cm/= 104 shows a broad maxinmum centered at about 1.70 Mev deuteron energy, on the other hand that from the increase with increasing deuteron energy, These results at our bombarding energies show that the reaction F/sup 19/(d,p)F/ sup 20/ seems to proceed mostly by compound nucleus formation, and the reaction F/ sup 19/(d,p)F/sup 20/ (0.65 Mev) seems to be caused by the stripping process of d neutrons.
