Abstract
The differential cross section for the quasi-free photoproduction reaction γn→K0Σ02400MeVΔ(1900)1/2-K∗ was measured at BGOOD at ELSA from threshold to a centre-of-mass energy of γn→K0Σ02400MeVΔ(1900)1/2-K∗. Close to threshold the results are consistent with existing data and are in agreement with partial wave analysis solutions over the full measured energy range, with a large coupling to the γn→K0Σ02400MeVΔ(1900)1/2-K∗ evident. This is the first dataset covering the γn→K0Σ02400MeVΔ(1900)1/2-K∗ threshold region, where there are model predictions of dynamically generated vector meson-baryon resonance contributions.
