• A high energy μ-meson Can produce π-meson, when it collides with a nucleon by its electromagnetic field. The energy dependency of the cross section for this process is analysed from the view point of the perturbation method including higher order corrections, when only the pseudo-scalar(direct)coupling of π-meson with nucleon is assumed. Next, retaining the character of the cross section thus obtained, we assume a phenomenological cross section for this process and apply it to the analysis of cosmic-ray burst underground. Then it is found that the consistency between the theory and the experiment seems not to be attainable, when only the direct coupling is taken into account. However, some remark are given on the information indicated by the burst experiment underground, before a definite conclusion is deduced.
