Isoscalar E0, E1, and E2 strength in Ca-40
Abstract
The giant resonance region from 10 particles at small angles including 0 degrees. Strength corresponding to 97 +/- 11%, 108 +/- 12%, and 62 + 10-20 % of the isoscalar E0, E2, and E1 sum rules, respectively, was identified with centroids of 19.18 +/- 0.37 MeV, 17.84 +/- 0.43 MeV, 23.36 +/- 0.70 MeV, and rms widths of 4.88 +/- 0.57 MeV, 2.89 +/- 0.60 MeV, and 5.34 +/- 0.90 MeV.
