TL;DR
This paper calculates the coherent photoproduction of two neutral pions on light nuclei, analyzing the dependence on isospin and fitting elementary amplitudes to experimental data.
Contribution
It provides a theoretical calculation of neutral pion pair photoproduction on light nuclei, incorporating isospin effects and fitting to experimental cross sections.
Findings
Cross sections depend on the target nucleus's isospin.
Elementary amplitudes fitted to proton and neutron data.
Discussion of isospin dependence in coherent photoproduction.
Abstract
Coherent photoproduction of two neutral pions on the deuteron and ^3He is calculated. The isoscalar and isovector parts of the elementary photoproduction amplitude was determined by fitting the measured total cross section on protons and neutrons. The dependence of the cross section on the isospin of the target nucleus is discussed.
