摘要
The low-energy (K) over bar N interaction is satisfactorily described by the constituent quark model with meson-quark couplings when the model is supplemented with a separable potential representing ''non-isobar'' contributions. The model is applied to the study of the radiative decays of kaonic hydrogen. The electromagnetic couplings of the quark- and mesonic-currents are defined in a phenomenological way. The calculated radiative decay widths of kaonic hydrogen agree with the experimental values fairly well. The meson-baryon interaction plays an important role as the initial state interaction in these radiative transitions.
