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 (-5[1])makes an unbound system. On charts depicting possible examples of these structures, stability occurs between the “drip lines.” (15[1])Terms proportional to A, (15[1])A to the two-thirds, and Z squared over A to (15[1])the one-third quantify the volume, surface, and (*) Coulomb contributions to the (10[1])energy (10[1])of these structures, (10[1])according (10[1])to a formula (10[1]-5[1])derived from the liquid (10[1])drop model. (10[3])The mass (10[1])defect of these structures is proportional to the (10[1])binding (10[1])energy required to separate (10[1])them (10[1])into their constituent (10[1])particles. For (10[1])10 points, what (10[1])structures were discovered when a beam of alpha particles (10[1])was deflected (10[2])by a gold foil? (10[1])■END■
