The reaction d(<(gamma)over right arrow>, np) has been studied using the tagged and polarised LADON gamma ray beam at an energy 30-50 MeV to investigate the existence of narrow dibaryonic resonances recently suggested from the experimental measurements in a different laboratory. The beam was obtained by Compton back-scattering of laser light on the electrons of the storage ring ADONE. Photo-neutron yields were measured at five neutron angle nu(n)(c.m.) = 22 degrees, 55.5 degrees, 90 degrees, 125 degrees and 157 degrees in the center of mass system. Our results do not support the existence of such resonances. (C) 1998 Published by Elsevier Science B.V.
