Angular distribution of the {ital L}{sub {ital l}} x-ray line (3{ital s}{sub 1/2}{r_arrow}2{ital p}{sub 3/2}) in Au and Bi induced by 3{endash}9 MeV carbon ions has been measured. Values of the alignment parameter ({ital A}{sub 2}) of the {ital L}{sub 3}(2{ital p}{sub 3/2}) subshell have been obtained from the data as a function of the carbon ion energy. The data have been compared with the calculations of the standard perturbed-stationary-state (PSS) theory with energy-loss (E), Coulomb deflection (C), and relativistic (R) corrections (ECPSSR) and ECPSSR with the intrashell (IS) effect included as a multiplicative factor. From this comparison it is evident that an account for the IS coupling substantially improves agreement between theory and measurement. The effect of simultaneous multiple ionization of the {ital M} and higher shells on the measured {ital A}{sub 2} values is discussed. {copyright} {ital 1996 The American Physical Society.}
