The angle-differential cross sections of neutron-induced deuteron production from carbon were meas-ured at six neutron energies from 25 to 52 MeV relative to those of n-p elastic scattering at the China Spallation Neutron Source (CSNS) Back-n white neutron source.By employing the AE-E telescopes of the Light-charged Particle Detector Array (LPDA) system at 15.1° to 55.0° in the laboratory system,ratios of the angle-differential cross sections of the 12C(n,xd) reactions to those of the n-p scattering were measured,and then,the angle-differen-tial cross sections of the 12C(n,xd) reactions were obtained using the angle-differential cross sections of the n-p elast-ic scattering from the JENDL-4.0/HE-2015 library as the standard.The obtained results are compared with data from previous measurements,all of which are based on mono-energic neutrons,the evaluated data from the JENDL-4.0/HE-2015 library and the ENDF-B/VIII.0 library,and those from theoretical calculations based on INCA code and Talys-1.9 code.Being the first white-neutron-source-based systematic measurement of the angle-differential cross sections of neutron-induced deuteron production reactions on carbon in several tens of MeV,the present work can provide a reference to the data library considering the lack of experimental data.

The Back-n white neutron source (known as Back-n) is based on back-streaming neutrons from the spal-lation target at the China Spallation Neutron Source (CSNS).With its excellent beam properties,e.g.,a neutron flux of approximately 1.8×107 n/cm2/s at 55 m
From a Bayesian analysis of the electric dipole polarizability,the constrained energy of isovector giant dipole resonance,the peak energy of isocalar giant quadrupole resonance,and the constrained energy of isocalar gi-ant monopole resonance in 208Pb,we e
In this article,we consider the ratio of structure functions for heavy quark pair production at low values of x.The importance of this ratio for charm and beauty pair production is examined according to the Hadron Elec-tron Ring Accelerator (HERA) data.Th
Neutrons tunneling to the classically forbidden (CF) region in the neutron-rich nucleus 68Ca are invest-igated in the Skyrme Hartree-Fock (HF) and Hartree-Fock-Bogoliubov (HFB) models.The definition of the CF re-gion is examined in the HF model by using d
In this paper,we explore the properties of holographic entanglement entropy (HEE),mutual information(MI) and entanglement of purification (EoP) in holographic Lifshitz theory.These informational quantities exhibit some universal properties of holographic
In this paper,we analyze the dependence of the topological charge density from the overlap operator on the Wilson mass parameter in the overlap kernel by the symmetric multi-probing source (SMP) method.We observe that non-trivial topological objects are r
The tensor-force effects on the evolution of spin-orbit splittings in neutron drops are investigated within the framework of the relativistic Hartree-Fock theory.For a fair comparison on the pure mean-field level,the results of the relativistic Brueckner-
We explore the effects of the density dependence of symmetry energy on the crust-core phase transition and dynamical instabilities in cold and warm neutron stars in the relativistic mean field (RMF) theory with point-coupling interactions using the Vlasov
Deep learning has been widely and actively used in various research areas.Recently,in gauge/gravity duality,a new deep learning technique called AdS/DL (Deep Learning) has been proposed.The goal of this paper is to explain the essence of AdS/DL in the sim
The two-photon-exchange (TPE) effect plays a key role in extracting the form factors (FFs) of the pro-ton.In this work,we discuss several exact properties of the TPE effect in the elastic ep scattering.By taking four low energy interactions as examples,we
