Abstract

The photonuclear cross section for the isovector electric dipole in ¹⁸O is calculated using the open-shell linear response method. The model accounts for the pygmy resonance and provides a simple interpretation for the main peak at 23.7 MeV observed in photoabsorption cross sections. The model reproduces qualitatively the main differences and common features of the ¹⁶O and ¹⁸O photoabsorption cross sections. The strength distributions of the isoscalar quadrupole and octupole states in ¹⁸O are also presented.

Charged photoparticles from the <sup>18</sup>O giant resonance
1982, Nuclear Physics, Section A
Emission of charged photoparticles from the ¹⁸O giant E1 resonance region was investigated at the University of Giessen electron linac at bremsstrahlung endpoint energies of 24 and 32 MeV. Spectra of protons, deuterons, tritons and α-particles were measured at six angles. Proton decay shows strong transitions to excited states in ¹⁷N. Deuterons and tritons have a nearly isotropic angular distribution. The ¹⁸O(γ, t₀)¹⁵N and the ¹⁸O(γ, α₀)¹⁴C cross sections are determined in the giant E1 resonance region. E1 and E2 ¹⁸O(γ, α₀¹⁴C cross sections are derived from the angular distribution measurement.
