通过对CaO和TiO_2晶体中短寿命β发射核~（19）O（Iπ=5/2+，T_（1/2）=27 s）的β-NMR谱的探测，确定了短寿命β发射核~（19）O的核磁偶极矩μ和电四极矩Q值，并对短寿命β发射核~（19）O的β-NMR谱进行了讨论。|μ| =（1.53195±0.00007）μ N，|Q| =（3.7±0.4）mb。这两个值从Hartree-Fock计算给出的壳模型预测的轻微偏差需要进一步的实验和理论研究。
The nuclear magnetic-dipole moment μ and electric-quadrupole moment Q of the short-lived β-emitting nucleus19O (Iπ=5/2+,T1/2=27 s ) have been determined by detecting its β-NMR in CaO and TiO2crystals to be |μ|=(1.53195±0.00007) μNand |Q|=(3.7±0.4) mb, respectively. Slight deviations of both values from the shell model predictions given by Hartree-Fock calculations demand further experimental and theoretical studies.
