“…In these molecules several temperature-dependent vibrational modes are possible, which alter the scattering cross section [35]. This is of particular relevance to this study and radiative capture on hydrogen is enhanced by ∼20% over the standard model.…”

Plastic scintillators are widely used in industry, medicine, and scientific research, including nuclear and particle physics. Although one of their most common applications is in neutron detection, experimental data on their response to low-energy nuclear recoils are scarce. Here, the relative scintillation efficiency for neutroninduced nuclear recoils in a polystyrene-based plastic scintillator (UPS-923A) is presented, exploring recoil energies between 125 and 850 keV. Monte Carlo simulations, incorporating light collection efficiency and energy resolution effects, are used to generate neutron scattering spectra which are matched to observed distributions of scintillation signals to parameterize the energy-dependent quenching factor. At energies above 300 keV the dependence is reasonably described using the semiempirical formulation of Birks and a kB factor of (0.014 ± 0.002) g MeV −1 cm −2 has been determined. Below that energy, the measured quenching factor falls more steeply than predicted by the Birks formalism.

“…Neutron interactions below 20 MeV are described by high-precision data-driven models with data obtained from the ENDF/B-VII library [38]. Additionally, thermal scattering off chemically bound atoms was implemented for neutron energies below 4 eV, which is especially important to model thermalisation in the plastics [39].…”

A measurement is presented of the neutron production rate in lead by high energy cosmic-ray muons at a depth of 2850 m water equivalent (w.e.) and a mean muon energy of 260 GeV. The measurement exploits the delayed coincidences between muons and the radiative capture of induced neutrons in a highly segmented tonne scale plastic scintillator detector. Detailed Monte Carlo simulations reproduce well the measured capture times and multiplicities and, within the dynamic range of the instrumentation, the spectrum of energy deposits. By comparing measurements with simulations of neutron capture rates a neutron yield in lead of (5.78) has been obtained. Absolute agreement between simulation and data is of order 25%. Consequences for deep underground rare event searches are discussed.

“…Thus, at these energies, specific features such as the binding properties of the molecule of interest must be included in neutron scattering (for a detailed discussion see Refs. [18,23]). A listing of the used GEANT4 neutron processes and datasets is given in Table 1.…”
