Thin targets of La, Pr, Nd, Eu, Tb, Ho and Er were bombarded by 1
H, 2
H, 3
He and 4
He projectiles. The production cross sections for the Lalpha 1,2
, L beta 1,3,4,6
, L beta 2,7,9,10,15
, L gamma 1,5
, Lgamma 2,3,L gamma 4,4and LlX-ray transitions have been extracted and corresponding ionization cross sections for L1
-, L2
- and L3
-subshells have been calculated. The ratios of the experimental data to the predictions of the ECPSSR and the SCA theories are presented as a function of the corrected reduced projectile velocity parameter xi Lir
. The Coulomb deflection of the projectile by the target nucleus predicted by these two approaches is compared with the experimental data. Possible reasons for the observed disagreement between experiment and theory are discussed.
