In the present work, the effect of Lambda(1405) resonant state on the neutrons momentum and energy spectra due to a stopped kaon on deuteron is studied within the coupled-channel approach, employing Argonne V18SC potential to describe nucleon-nucleon interaction. For this purpose, both chiral and phenomenological potentials with different one-pole and two-pole structures have been used to investigate the dependence of the neutrons spectrum resulting from the interaction on the different models. In the following, using the Akaishi-Yamazaki model, we have shown that the Lambda(1405) resonance trace is clearly visible in such spectra. Our results indicate that a detailed study of the kaon–deuteron interaction can significantly contribute to improving our understanding of the KN-πƩ interaction and the nature of theresonance.
