We present a preliminary analysis of the photon beam asymmetry observable (Σ) from the photoproduction reaction channel γn → π-p. This new data was obtained using the near-4π CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Laboratory, USA, employing a linearly polarised photon beam with an energy range 1.1 - 2.3 GeV. The measurement will provide new data to address the poorly established neutron excitation spectrum and will greatly expand the sparse world data-set both in energy and angle.

The energy dependence of the electric dipole amplitude, the total and differential cross-sections of the photoproduction of neutral pions off protons near threshold is given. The amplitude of process is a sum of the LET prediction and the additional term connected with the chiral symmetry breaking interaction. The simple K-matrix calculations are used to estimate the change in the electric dipole amplitude and the total and differential cross-sections between π0p and π+n thresholds.
