WebAlpha Decay (2 4He): An alpha (α) particle {2 4He (nucleus only) } is emitted. An alpha particle barely passes through paper , since it is a helium nucleus, which is fairly large . The atoms in the paper will slow and eventually stop (if the paper is thick enough) the alpha partic le as it attempts to move through the paper atoms. WebBecause its half life is so long, scientists can keep the target for a long number of years. In 1944 a 239Pu target was bombarded with alpha particles at the 60-Inch Cyclotron to produce curium (Cm, Z = 96) through the following nuclear reaction 239Pu (24,110 yr) + 4He ®242Cm (162.8 d) + 1n.

Neutrons may be captured by non-fissile nuclei, and some energy is produced by this mechanism in the form of gamma rays as the compound nucleus de-excites. The resultant new nucleus may become more stable by emitting alpha or beta particles.
