Additionally the use of a coincidence regime of registration of [beta]-decay events will allow us to considerably suppress the background, and to separate effect and background by means of the delayed coincidence method.
A decay event is identified by a delayed coincidence between a fast electron (TOF[approximately equal to]10 ns) and a slow proton (TOF on the order of tens of microseconds).
This is a delayed coincidence experiment, so only accidental coincidences from background radiation will appear as background events in the data.
Figure 6 shows the timing spectrum of protons in delayed coincidence with electrons where each channel corresponds to 12.
