Because of the light mass, the recoil effect is strong after the particle is emitted, so the recoil effect is must taken into account to maintain the energy balance.
由于轻核质量轻，发射粒子后反冲效应很强，理论计算中还严格考虑了反冲效应的影响，从而保证了能量守恒。

The associated particle method was used to determine the absolute neutron flux and compared with the recoil proton telescope. The agreement between both methods appeared to be within 1—2%.
