摘要: A very drastic change in the present conception of interaction mesons with atomic nuclei was suggested by Fermi, Teller and Weisskopf1 as a result experiments Conversi, Pancini Piccioni2, who observed behaviour positive negative cosmic ray coming to rest iron or graphite. They find that iron, disintegration electrons are only for mesons. According Tomonaga Araki3, this is be expected because mesons—in contrast ones—after being slowed down can approach nucleus absorbed it view strong postulated Yukawa explain nuclear forces. In graphite, on other hand, decay were from both Fermi et al. concluded sharp disagreement expectation, according their estimate takes about 10–12 sec. until meson solid reaches its lowest orbit, which should captured less than 10–18 Since natural time 10–6 sec., they conclude no expected, experimental evidence
