Title: NEW CALCULATION OF RADIOACTIVE SECONDARIES IN COSMIC RAYS

We use a new version of our numerical model for particle propagation in the Galaxy to study radioactive secondaries. For evaluation of the production cross sections we use the Los Alamos compilation of all available experimental cross sections together with calculations using the improved Cascade-Exciton Model code CEM2k. Using the radioactive secondary ratios {sup 26}Al/{sup 27}Al, {sup 36}Cl/Cl, {sup 54}Mn/Mn, we show how the improved cross-section calculations together with the new propagation code allow us to better constrain the size of the CR halo.
