Saclay and Argonne see nuclear quartet states

JUL 01, 1971

DOI: 10.1063/1.3022838

If you bombard Fe56 with O16 ions, you can observe C12 ions being emitted, which means that an alpha particle (really two protons and two neutrons whose relative motions are probably correlated as they are in an alpha particle) has been incorporated in the residual nucleus—in this case Ni60. The spectrum shows certain selected states and not others. That is, at certain specific energies the alpha particles find an easy way to get in—the system appears to resonate. Such experiments with alpha‐particle transfer reactions are exciting great interest among nuclear physicists.
