We calculate a power series expansion of the generalized oscillator strengt
h for forbidden excitations by electron impact in Li-like Al, configuration
1s(2) nl, in jj-coupling. In our method we use a configuration interaction
expansion for the target wave function including configurations 1s(2) nl w
ith n less than or equal to 5. These results are believed to be the first s
uch values for this system and will be important in plasma modelling.
