Alpha bombardment of nitrogen produced hydrogen nuclei, establishing the proton as a nuclear constituent and demonstrating artificial transmutation.
wp-physics-protondoe-protonspdg-rppEach relation below ends at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
The transmutation experiment established the hydrogen nucleus as a recurring nuclear constituent identified with the proton.
The source theory, law, entity, prediction, or structural claim is directly tested, supported, constrained, or established by the target experiment or observation. Experimental support is not final logical proof; the edge detail states exactly what was measured.
