我们研究了时间为$ensuremath{lesssim}{10}^{ensuremath{-}4}{t}_{frac{1}{2}}$的{60}主元{Co}$和区间$0.3{t}_{frac{1}{2}}ensuremath{le}tensuremath{le}45{t}_{frac{1}{2}}$内的{56}主元{Mn}的衰变，分别在短时间和长时间寻找偏离指数衰变规律的建议偏差。在考察的所有时间段内，我们的数据都符合纯粹的指数行为。根据这些测量，对可能偏离指数衰减定律的幅度得出了严格的限制。
We have studied the $ensuremath{eta}$ decays of $^{60}mathrm{Co}$ at times $ensuremath{lesssim}{10}^{ensuremath{-}4}{t}_{frac{1}{2}}$ and those of $^{56}mathrm{Mn}$ over the interval $0.3{t}_{frac{1}{2}}ensuremath{le}tensuremath{le}45{t}_{frac{1}{2}}$ to search for proposed deviations from the exponential decay law at short and long times, respectively. Over all time periods examined, our data are consistent with purely exponential behavior. From these measurements, stringent limits are derived on the amplitudes of possible deviations from the exponential decay law.
