“…The rejection of the e.m. background was facilitated by the fact that in our target the form of the pulse associated with the detection of a hadron is different from that of an electron/photon, thus we have used the Head-Tail [14][15][16][17][18] technique. The Head is defined as the integral of the entire pulse, which is the signal which provides the energy of proton, while the Tail is the integral of the last part of it.…”

The reaction d( γ, np) has been studied using the tagged and polarised LADON gamma ray beam at an energy 30 − 50 M eV to investigate the existence of narrow dibaryonic resonances recently suggested from the experimental measurements in a different laboratory. The beam was obtained by Compton back-scattering of laser light on the electrons of the storage ring ADONE. Photo-neutron yields were measured at five neutron angle ϑ c.m.

“…As the total photoelectron number n is proportional to the energy deposition of radiation inside the scintillator, and the number of photoelectrons per keV energy loss in the scintillator for BC501A is about 1.7/keV [9], with the assumption that the ratios of photons to neutrons in calculations are to be one, the calculation results can predict the intrinsic n-γ discrimination to be compared with the experimental results. The corresponding parameters for the rise time distribution calculation are listed in Table 1.…”

“…In this case, the high energy neutron and gamma concealed the actual n-γ discrimination capability of the low energy. Besides, some statistical models have been built and studied since 1950s [8][9][10][11][12][13] not only for the evaluation of scintillation materials but also for the optimization of PSD parameters and the comparison of PSD methods. However, there is no report about the comparative and quantitative study of the n-γ discrimination performance between the rise-time method and the zero-crossing method focused on the low energy region.…”

The n-γ discrimination performance of two experimental arrangements based on the rise-time method and the zero-crossing method was compared for a 50.8 mm-diametered and 50.8 mm-high BC501A liquid scintillator coupled to a 50.8 mm-diametered 9807B photomultiplier in this work. The low energy limitation of the detected neutron with different detector high voltages and the figure of merit of the n-γ discrimination in four neutron energy regions (1-2 MeV, 0.75-1 MeV, 0.5-0.75 MeV and below 0.5 MeV) were studied by using the Am-Be neutron source. Under a time statistical model of the photoelectron emission process in scintillation counters, the intrinsic capability of the n-γ discrimination performance under the optimal condition was evaluated. The experimental results of the zero-crossing method demonstrate a better n-γ. discrimination performance than those of the rise-time method, which is consistent with the calculated results. rise-time method, zero-crossing method, n-g discrimination, time statistics analysis, BC501A scintillation detector PACS: 29.40.Mc, 07.05.Tp

“…This is possible because the time dependence of the pulse intensity is different for gammas and neutrons (ref. 35). The anode pulse is analyzed for its fast component while the slow component is found by examining the thirteenth dynode pulse.…”
