A novel technique, using secondary forward recoil ions generated in th
in standard targets by energetic very heavy primary ion beam, has been
employed to measure energy loss of several ion species (Z(1) = 8 to 2
9) covering energies between 0.1 and 1.0 MeV/u. Energy variation was s
imply affected by changing the detector angle between 35 degrees to 70
degrees, avoiding the dominant elastic scattering of the primary beam
. A twin detector permitted simultaneous measurement of both unabsorbe
d and absorbed spectra. The experimental data on stopping power are co
mpared with evaluated values using LSS theory and TRIM. A better under
standing of the validity of available theoretical evaluations has beco
me possible, with a need for higher precision in experimental data in
some cases.
