  In this work, we reexamine the extension of the CDCC formalism to include
target excitation and apply it to a variety of reactions to study the effect of
breakup on inelastic cross sections. We use a transformed oscillator basis to
discretize the continuum of the projectiles in the different reactions and use
the extended CDCC method developed in this work to solve the resulting coupled
differential equations. A new code has been developed to perform the
calculations. Reactions 58Ni(d, d) 58Ni*, 24Mg(d, d) 24Mg* , 144Sm( 6Li, 6Li)
144Sm* and 9Be( 6Li, 6Li) 9Be* are studied. Satisfactory agreement is found
between experimental data and extended CDCC calculations. The studied CDCC
method is proved to be an accurate tool to describe target excitation in
reactions with weakly-bound nuclei. Moderate effects of breakup on inelastic
observables are found for the reactions studied. Cross section magnitudes are
not modified much, but angular distributions present smoothing when opposed to
calculations without breakup.
