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. WebThe bombarding particle may be an alpha particle, a gamma-ray photon, a neutron, a proton, or a heavy ion. In any case, the bombarding particle must have enough energy to …
