Asymmetries in some partnered examples of these structures may produce a Thomas-Ehrman shift. Some three-component “halo” examples of these structures may also be “Borromean,” since removing any component (15[1]-5[1])makes an unbound system. On charts depicting possible examples of these structures, stability occurs between the “drip lines.” (15[2])Terms proportional to A, (15[1])A to the two-thirds, and Z squared over A to the one-third quantify the volume, surface, and (*) Coulomb (10[1])contributions (10[1])to the energy (10[2])of these structures, (10[1])according to a formula (10[1]-5[1])derived from the liquid drop model. (10[4])The mass (10[1])defect of these structures is proportional to the binding energy (10[1])required to separate (10[1])them (10[1])into (10[1])their constituent particles. (10[1])For 10 points, what structures were discovered when a beam of alpha particles (10[1])was deflected (10[2])by a gold foil? (10[1])■END■
