在14.7 ± 0.2MeV处发现了一个新的共振峰。峰值耗尽的E0总和规则的一个重要部分，其特征在于约2.1兆电子伏的窄宽度。巨四极共振在9.5 ± 0.2和11.3 ± 0.2 MeV处分裂成两个峰，分别消耗了等oscillator E2能量加权和规则的（29 ± 5）%和（63 ± 8）%。
A new resonance peak has been found at 14.7 +- 0.2 MeV in spectra of inelastic electrons scattered from /sup 181/Ta. The peak exhausts a significant part of the E0 sum rule and is characterized by a narrow width of about 2.1 MeV. The giant quadrupole resonances splits into two peaks at 9.5 +- 0.2 and 11.3 +- 0.2 MeV which deplete (29 +- 5) % and (63 +- 8) % of the isoscalar E2 energy-weighted sum rule, respectively.
