Gamma–gamma coincidence spectrometer setup for neutron activation analysis and nuclear structure studies

Gamma Cascade Transition of <sup>51</sup>V(n<sub>th</sub>, <i>g </i>)<sup>52</sup>V Reaction

“…Two plates of 2 mm thick lead were placed between the detectors and target to decrease the number of backscattered gamma rays and to filter out X-ray. The electronics configuration was used in those gammagamma coincidence experiments are shown in Figure 1, the parameters of system were setup by method in Reference [9]. The detector signals are amplified with 572 amplifier (AMP) modules with a shaping time of 3.0 µs and about 1 keV per channel.…”

First results in the study of level scheme for ¹⁷²Yb based on gamma-gamma coincidence spectrometer

“…The gamma-gamma coincidence method [4][5][6] has advantages in achieving the low Compton background and identifying the correlated gamma transitions. The advantages not only improve the detection limit gamma transition from (n,γ) reaction but also provide information of state, from which secondary transition decays.…”

“…For this reason, wehave measured the gamma cascades of 172 Yb from 171 Yb(n,γ) 172 Yb reaction using the gammagamma coincidence spectrometer [5] with 10 times statistics higher than reported in ref [7], for the aim of improving knowledge of level scheme of 172 Yb.…”

Determination of selenium in environmental sample by gammagamma Coincidence method

“…Recently, the gamma-gamma coincidence methods have been shown to give accurate determination of Se in geological sample in Dalat Nuclear Research Reactor [1], and the interference of other gamma rays at the energy of interest such as the 152 Eu, 181 Hf and 182 Ta lines which interfere with the detection of 75 Se were solved without the need for radiochemical separation. This work, we applied processes the same described in Reference [1], in order to [7] determine Se in environmental sample by gammagamma coincidence method.…”
