Cross sections of the 6Li(n, t)4He reaction were measured in the fast neutron energy range from 3.3 to 5.3 MeV using a gridded ionization chamber (GIC) and well–calibrated experimental setup at the EG–5 Van de Graaff accelerator of the Frank Laboratory of Neutron Physics, Joint Institute for Nuclear Research (FLNP, JINR). Lithium fluoride (6LiF) samples with varying thicknesses and krypton–CO2 gas mixtures with different pressures were used to optimize the detection of both alpha particles and tritons. Neutron fluxes were monitored using two high–purity (99.999%) 238U3O8 samples placed inside the GIC, complemented by an externally calibrated 3He long counter. The measured 6Li(n, t)4He cross–section data were compared with existing results of measurements and evaluations from EXFOR and ENDF nuclear data libraries, and the results showed a good agreement in the measured neutron energy range. These new measurements provide reliable cross–section data that contribute to the refinement of evaluated nuclear data files and support applications in nuclear physics, tritium production, and reactor design.
Our analysis reveals the significant influence of continuum states in close proximity to the resonant pole on both phase shifts and continuum level densities. Specifically, the uppermost and lowest continuum states, located just above and below the resonant pole, make substantial contributions to the scattering quantities. Conversely, the continuum state located farthest from the resonant pole has a negligible impact. These findings underscore the crucial role of continuum state structure in understanding physical observables in light nuclei. This work focuses on a detailed investigation of the 3=2 state 5Li
We present our recent results of the mirror nuclei 5He and 5Li obtained by analyzing structure of continuum states in the complex scaled α + N two-body model. Decomposed scattering cross section and continuum level density of α + N system are discussed.
The purpose of this work is to investigate the reliability of the virtual state solutions in the CSM as comparing with the solutions of the Jost function method. To investigate the structure of the virtual state, we calculate the energy eigenvalues, phase shifts and photodisintegration cross section of the two-body model with a two-range Gaussian potential by changing the strength of the attractive potential.
In this work we investigate the higher excited states of a+a system applying the complex scaling method. The low-lying 0+ , 2+ and 4+ states of a+a are measured well but the higher excited states 6+ , 8+ and 10+ of a+a are not available by experimentally and these higher excited states have been barely studied by theoretical approaches.
