Energies of Natural Alpha Radiators

Conference paper


More than 60% of the Q-value measurements of charged primary particle reactions used in nuclidic mass adjustments have been calibrated with natural α-particle energy standards, predominantly 210Po; in some other cases, 212Po and 212Bi have been used. 214Po has been used in a few relative measurements of reaction energy standards. Additional application of absolute α-energies is found in α-spectroscopy, where even less abundant α-groups are useful, in order to cover the full range between 4 and 10 MeV.
