“…On the basis of the united Hauser-Feshbach and exciton model, after considering emission rates of the nucleon (neutron and proton) [37] and complex particle [28,[38][39][40] in equilibrium and preequilibrium states, the expressions of the outgoing particle double-differential cross sections are obtained formally as…”

On the basis of the statistical theory of a neutron-induced light nucleus reaction, a new kerma coefficient calculation formula, expressed as k = N ij k E ij k (E n )σ ij k (E n ), is developed in this paper. In an analysis of the n + 12 C and n + 16 O reactions below 30 MeV, the average energies E ij k of emitted particles of all kinds in the laboratory frame are derived in detail for different channels, allowing an exact energy balance. The optical model parameters of neutron and charged particles, which had reproduced very well the outgoing neutron double-differential cross sections in our early works, are used to obtain the cross sections σ ij k . The calculated partial, elastic recoil, and total kerma coefficients for carbon and oxygen are consistent with existing experimental kerma coefficient data. The elastic cross sections and the first Legendre coefficients of elastic angular distribution derived from EBDF/B-VIIb3 are used in this paper to improve significantly the elastic recoil and total kerma coefficients.

“…[1−4] The total outgoing neutron doubledifferential cross sections consist of the neutrons emitted from various reaction channels to discrete levels of residual nucleus, which strongly differ from each other. It has shown that 5 He emission should be taken into account for fitting the experimental data. Otherwise, obvious deficiency will appear at low energy part of neutron emission angle-energy spectra, which can be reparative when the 5 He emission channel has been considered.…”

“…Based on the idea of Iwamoto-Harada model, it has been extended to the composite particle of 5 He cluster including 1p shell nucleon, and the formulation of the pre-formation probability in compound nucleus for 5 He has been established and calculated. Compared with the results of pre-formation probabilities for other composite particles, the calculated results for 5 He cluster is reasonable. The basic idea of the Iwamoto-Harada model is introduced in Sec.…”

The possibility of 5 He cluster emission has been affirmed theoretically. In order to describe the emission probability of 5 He cluster, the pre-formation probability of 5 He cluster in pre-equilibrium emission process is needed to be established. In terms of Iwamoto-Harada model, the theoretical formula of pre-formation probability of 5 He cluster including 1p shell nucleon in pre-equilibrium mechanism has been established and calculated. In the case of low incident energies, the configuration of [1, m] for 5 He cluster is the dominant part in the nuclear reaction. The calculated results indicate that pre-formation probability of configuration [1, m] for the unstable 5 He cluster is much smaller than those of d, t, 3 He, and 4 He, i.e. the light stable composite particles, which are consisted of only 1s shell nucleons. However, it is propitious to the emission of 5 He from the point of view on threshold energies, since the binding energies of 5 He are generally lower than that of 3 He in compound nucleus. The corresponding model formula has been given in this paper for described pre-formation probability of 5 He cluster in pre-equilibrium mechanism.

Sodium‐ion batteries (SIBs) reflect a strategic move for scalable and sustainable energy storage. The focus on high‐entropy (HE) cathode materials, particularly layered oxides, has ignited scientific interest due to the unique characteristics and effects to tackle their shortcomings, such as inferior structural stability, sluggish reaction kinetics, severe Jahn‐Teller effects induced lattice distortion, and poor oxygen reversibility at high voltage. This review focuses on high‐entropy oxide materials, highlighting their fundamentals, design principles, and application in layered oxide cathodes for SIBs. It delves into the growth mechanism, composition‐properties correlations, and the functional roles of high‐entropy design in enhancing the performance of layered oxide cathodes. Furthermore, it furnishes a comprehensive survey of recent advancements and persisting challenges within the domain of layered high‐entropy cathode materials, as well as offers insights into potential future research directions in line with the current state of knowledge.
