Lub neutron lub neej yog theorized los ntawm Rutherford nyob rau hauv 1920 thiab nrhiav tau los ntawm Chadwick hauv 1932, raws li American Physical Society. Neutrons tau pom nyob rau hauv kev sim thaum atoms raug tua ntawm ib daim ntawv nyias ntawm beryllium. Subatomic hais uas tsis muaj nqi raug tso tawm - cov neutron.
