Abstract

We propose two types of neutron-γ1\gamma_1-γ2\gamma_2 triple coincidence detectors (not constructed) to chase gamma transitions to produce p-nuclei following the neutron emission in the (γ,n)(\gamma, n) reaction. Neutrons are detected with 24 3^3He counters embedded in a polyethylene moderator in Type I detector and with 6 liquid scintillation detectors in Type II detector, respectively. γ\gamma rays are detected with two high-purity germanium detectors and four LaBr3_3(Ce) detectors. The detector which is referred to as p-process chaser detector is used to search for mediating states in 180^{180}Ta through which the isomeric and ground states in 180^{180}Ta are thermalized in the p-process. A search is made for both resonant states and unresolved states in high nuclear-level-density domain.
