Erratum: High energy component of giant octupole resonance in medium and heavy mass nuclei

Influence of collective nuclear vibrations on initial state eccentricities in Pb+Pb collisions

“…[58] (ω ≈ 19.6 ± 0.5 MeV, Γ ≈ 7.4 ± 0.6 MeV with the EWSR fraction 70 ± 14%) we obtain r 3 ≈ 0.84. However, if we take 25% for the EWSR fraction of the 2.615 MeV state as obtained in [61], and the parameters of the HEOR obtained in [63] (ω = 16 MeV, Γ = 6 MeV), then we obtain r 3 ≈ 0.7. Thus, we see that the experimental data on the octupole strength function of the 208 Pb nucleus support that r 3 ∼ < 1.…”

“…For the 208 Pb nucleus, the function S(ω) for the operator F 3 is distributed in a broad range of ω. There are several very narrow peaks in the low-energy region ω ∼ < 7 MeV, [59][60][61], in which the low lying 3 − state with ω ≈ 2.615 MeV exhausts ∼ 20 − 25% of the EWSR [59][60][61] and several more states in the region 4.7 ∼ < ω ∼ < 7 MeV (so called the low-energy octupole resonance (LEOR) region) that exhaust about 8 − 13% of the EWSR [59,60]. In the high-energy region there is a broad resonance at ω ∼ 16 − 20 MeV with Γ ∼ 5 − 8 Mev [58,[61][62][63][64][65].…”

Collective nuclear vibrations and initial state shape fluctuations in central Pb+Pb collisions: resolving the $v_2$ to $v_3$ puzzle

“…[24,37,38]). From the available experimental data [24,37,38] one can conclude that for L = 3 the ratio r given by ( 12) is close to one or a bit smaller. The octupole strength function calculated in [39] within the random phase approximation for the Skyrme interaction also leads to r ≈ 1.…”
