实验截面的反应在失踪的能量范围从0.017到0.022 GeV和高达失踪的动量为0.632 GeV/atand（GeV/）的报告。数据进行了比较，相对论扭曲波脉冲近似计算的thechannel。显著更多的事件被观察到forGeV/比预测的理论模型，和惊人的比值的数据的理论模型/周围的初始状态多核子相关性的可能信号。
Experimental cross sections for thereactions in the missing energy range from 0.017 to 0.022 GeV and up to a missing momentum of 0.632 GeV/atand(GeV/are reported. The data are compared to relativistic distorted-wave impulse approximation calculations for thechannel. Significantly more events are observed forGeV/than are predicted by the theoretical model, and striking fluctuations in the ratio of data to the theoretical model around/are possible signals of initial-state multinucleon correlations.
