本文研究了E/A=100 MeV的~（60）Ni（~（13）C，~（13）N）~（60）Co的电荷交换反应，确定了等矢量（δ T =1）非自旋翻转（δ S =0）巨共振的位置。除了在E（x）= 8.7MeV处观察到巨偶极共振外，在E（x）=20 MeV处还观察到另一个宽为9 MeV的共振。扭曲波玻恩近似分析的角分布清楚地表明，L=2多极，归因于E（x）=20 MeV的状态的巨大的等矢量四极共振。
The charge-exchange reaction 60Ni(13C,13N)60Co at E/A=100 MeV has been studied to locate isovector (deltaT=1) non-spin-flip (deltaS=0) giant resonances. Besides the giant dipole resonance at E(x)=8.7 MeV, another resonance has been observed at E(x)=20 MeV with a width of 9 MeV. Distorted-wave Born approximation analysis on the angular distribution clearly indicated the L=2 multipolarity, attributing the E(x)=20 MeV state to the giant isovector quadrupole resonance.
