绝对测量的亚临界度进行了使用中子相关技术，使用三阶矩的中子数在京都大学临界大会进行的实验中检测到的。虽然实验误差不小，但可以确认，当仔细选择中子探测器和外部中子源的位置时，本技术可以粗略地给出低至4.5%K/K的亚临界度的绝对值。
Absolute measurement of the subcriticality was carried out by using a neutron correlation technique that uses a third order moment of the number of neutrons detected in the experiments carried out at the Kyoto University Critical Assembly. Although the experimental errors were not so small, it was confirmed that the present technique could roughly give absolute values of the subcriticality of down to 4.5 %∆k/k when locations of the neutron detector and the extraneous neutron source were carefully chosen.
