Effective photoexcitation cross section of115In(γ,γ′)115mIn from photoactivation data

Extracting the dipole cross-section from photo- and electro-production total cross-section data

We report on a successful attempt to extract the cross-section for the high-energy scattering of colour dipoles of fixed transverse size off protons using electroproduction and photoproduction total crosssection data, subject to the constraint provided by the ratio of the overall photon dissociation cross-section to the total cross-section. 13.60.Hb, 25.20.Lj, 25.30.Rw, 13.38.-t, 24.85.+p, 12.4...

p̄p low energy parameters from annihilation cross section data

Abstract. The recent experimental data obtained by the OBELIX group on total p̄p annihilation cross section are analysed; the low energy spin averaged parameters of the p̄p scattering amplitude (the imaginary parts of the S-wave scattering length and P-wave scattering volume) are extracted from the data. Their values are found to be equal to Imasc = −0.69±0.01(stat)±0.03(sys) fm, ImAsc = −0.76±0....

Photoabsorption Cross Section Revisited: Correlated HH versus Effective Interaction HH

Two conceptually different hyperspherical harmonics expansions are used for the calculation of the total He photoabsorption cross section. Besides the well known method of CHH the recently introduced effective interaction approach for the hyperspherical formalism is applied. Semi-realistic NN potentials are employed and final state interaction is fully taken into account via the Lorentz integra...
