The short range component of the nucleon-nucleus interaction is phenomenologically described by effective interaction including the so-called Landau-Migdal parameters g′, among which only g ΔΔ has been left unfixed because of the scarcity of experimental information. We propose Coherent Pion Production (CPP) measurement 12C(p, nπ+)12C(g.s.) to get quantitative information on gΔΔ. A preliminary CPP experiment was performed at the RCNP neutron time of flight facility by involving exclusive measurement of pions and neutrons. We have specially developed for this purpose a new pion counter and embedded it in the beam swinger magnet of the neutron time of flight facility. We describe the experiment and preliminary result from the pion-neutron coincidences.
