Nuclear quantum beats have been observed for an ensemble of one- and two-electron <sup>12</sup>Ne ions recoiling into vacuum following the reaction <sup>2</sup>H(<sup>20</sup>Ne,p)<sup>21</sup>Ne*. From the dominant frequency of the recoil-distance beat pattern observed in the singles gamma ray intensity a value for the g factor of mod g mod =0.196(14) was deduced for the 351 keV <sup>5</sup>/<sub>2</sub><sup>+</sup> state of <sup>21</sup>Ne. The experiment also led to values of 10.23(20)ps and 10.22(12)ps for the lifetimes of this state and of the mirror 332 keV <sup>5</sup>/<sub>2</sub><sup>+</sup> state of <sup>21</sup>Na respectively. Deductions were made of the degree of atomic excitation, within the nuclear lifetime, of the one- and two-electron neon ions.
