Measurement of production cross section is of significance to investigate the competition between compound nucleus and direct reaction mechanism, as well as for testing the validity of existing theoretical models I'2 The experimental information concerning alpha reaction cross sections in the earth region has until now been scarce. Early work on ion induced reactions on 159Tb was done previously 3-5
