Under certain circumstances, a nucleus can decay by emitting a particle more massive than an `alpha` -particle. Consider the following decay processes:
`""_(88)^(223)Ra to ""_(82)^(209)Pb +""_(6)^(14)C`
`""_(88)^(223)Ra to ""_(86)^(219_Rn+""_(2)^(4)He`
Calculate the Q-values for these decays and determine that both are energetically allowed.
