Isobar configurations: $\Delta N$ correlations versus the independent particle model

Autor: Glavanakov, I. V., Tabachenko, A. N.

We present a comparative analysis of two models for the $A( {\gamma,\,\pi N})B$ reaction, which take into account the isobar configurations in the ground state of the nuclei: the $\Delta N$ correlation model and the quasifree pion photoproduction mod

A model of $\pi N$ pair photoproduction on nuclei at high momentum transfer is presented. The $A(\gamma,\pi N)B$ reaction amplitude is obtained by means of an extended impulse approximation, according to which the nuclear wavefunction includes delta-

The differential cross section for the reaction $^{12}$C$(\gamma ,\pi ^{+}p)$ has been measured in the $\Delta$ resonance region at high recoil momenta of the residual nuclear system. The data are analysed under the assumption that the formation of $
