Many defend the thesis that when someone knows p, they couldn’t easily have been wrong about p. But notion of easy possibility in play is relatively under-theorized. One structural idea literature, principle Counterfactual Closure (CC), connects with counterfactuals: if it could happened and p were case then q would be case, follows q. We first argue that, while CC false, there a true restricti...

In this study, we compared double differential cross-sections (DDXs) between the experimental data obtained by 16.6 MeV of polarized photons and DDXs from JENDL2004 JENDL/PD-2016.1 for 197 Au, nat Pb, Cu, Ti targets. Using Python-based software, extracted nuclear libraries (NDLs), which were subsequently deduced considering abundances each target’s isotopes, width photon beam, energy resolution...

Pohang Neutron Facility (PNF) is a pulsed neutron facility based on the 100-MeV electron linear accelerator. It was constructed for nuclear data production in Korea, and it consists of an electron linear accelerator, a watercooled Ta target with a water moderator and a time-offlight path with an 11 m length. The 100-MeV electron linac uses a thermionic RF-gun, an alpha magnet, four quadrupole m...

It is difficult to reveal smuggled U-bearing material by passive gamma-detection, because the weak radiation can easily be shielded. Neutrons, as penetrate shielding, represent a detection potential, by inducing fission in the nuclear material. A 4 MeV linear accelerator was used as a pulsed neutron source for active interrogation of U-bearing material. Produced in heavy water by bremsstrahlung...

Intense, quasi-monochromatic, polarized $\gamma$-ray beams produced by Compton scattering of laser photons against relativistic electrons are used for fundamental studies and applications. Following a series photoneutron cross section measurements in the Giant Dipole Resonance energy region performed at NewSUBARU synchrotron radiation facility, we have developed eliLaBr Monte Carlo simulation c...
