Ranges and range straggling of recoils from nuclear reactions induced by the ions C/sup 12/, N/sup 14/, O/sup 16/, O/sup 18/ a nd Ne/sup 22/ with kinetic energies of 10 Mev per nucleon and less are reported. Range-energy curves were obtained for Tb/sup 149/ (recoil energies of 4 to 29 Mev) in Al, for At and Po (4 to 15 Mev) in Al, and for At and Po (4 to 9 Mev) in Au. Ranges of Tb/sup 149/ at the threshold of each reaction were obtained by extrapolation. The agreement of these and the directly measured values support the assumption of compoundnucleus formation used in calculating the recoil energies. The smaller recoil velocities in this study are of the same order as the Bohr velocity (2.2 x 10/sup 8/ cm/sec). The values of the average range and the straggling parameter are compared with stopping theory. The contribution to the measured range straggling from the nuclear reaction is discussed. These results and others were used to obtain values of the range for Xe/sup 139/ in Al from 0.1 to 70 Mev and for At/sup 203/ in Au from 0.01 to 10 Mev (auth)
