OBSERVATION AND STUDY ON THE PHENOMENA OF HEAVY PARTICLE EMISSION——A NEW KIND OF NATURAL RADIOACTIVITY, EVIDENCE OF THE EMISSION OF ^(12)C, ^(14)C and ^(16)O

Heavy particle emission phenomenon means some heavy neclei proceed spontaneously with carbon decay and oxygen decay, i. e. the phenomena that some heavy auclei can emit carbon nucleus and oxygen nucleus, besides the known α,β,γ, neutron and proton.
