Our results, obtained with the photon-conversion method, supplement the rather sparse information on neutral-meson production in proton-nucleus reactions existing for this bombarding energy regime. The reconstructed e+e−e+e− transverse-momentum and rapidity distributions are confronted with transport-model calculations, which account fairly well for both π0 and η production.engjournal article2019-02-03
