Gamma–gamma coincidence measurements following inelastic neutron scattering

Experiments on multiphonon states with proton–neutron mixed symmetry in vibrational nuclei

“…The kinetic energy of the neutrons can be controlled by adjusting the incident proton energies. Excited states of the secondary target nuclei can be populated up to the energy of the neutron beam and their decays can be studied by γ -ray spectroscopy [101]. The bottom part of Fig.…”

Nuclear Structure Studies of106Pd and106Cd with the (n,n′γ) Reaction

“…A γ-γ coincidence measurement was carried out for 106 Pd at a neutron energy of 3.3 MeV with four HPGe detectors placed ∼ 6 cm from the center of the sample in a co-planar arrangement [13]. Events were recorded when at least two detectors registered coincidences within a 100-ns time window.…”

Collective and two-quasiparticle excitations in128Te

“…The experimental arrangement is discussed in detail in Ref. [42]. A natural Te sample was hung coaxially with the beam, and four 50 to 55% efficiency HpGe detectors were placed in a co-planar arrangement approximately 6 cm from the center of the sample.…”

“…The gain stability of the system was monitored using 226 Ra and 152 Eu radioactive sources. The neutron scattering facilities, TOF neutron background suppression, neutron monitoring, and data reduction techniques have been described elsewhere [42,43].…”
