Beams of 96- and 129-MeV ..cap alpha.. particles were used to excite the giant resonance region in /sup 90/Zr and /sup 116/Sn. From the analysis of data obtained from 0/sup 0/ to 8/sup 0/, two distinct components of the giant resonance peak were resolved in each nucleus. The upper component is well described by a distorted-wave Born-approximation calculation for L=0 exhausting 90% (180%) of the energy weighted sum rule and has E/sub x/=16.2 MeV (15.6 MeV), GAMMA=3.5 MeV (4.1 MeV) for /sup 90/Zr (/sup 116/Sn). The nuclear incompressibility is extracted from these data and from that available for /sup 144/Sm and /sup 208/Pb. The lower component is the giant quadrupole resonance exhausting 66% (84%) of the isoscalar quadrupole sum rule and has E/sub x/=14.0 MeV (13.2 MeV), GAMMA=3.4 MeV (3.3 MeV) for /sup 90/Zr (/sup 116/Sn).
