Moreover, on the average, Γη increases in proportion to ε0½ therefore, reduced neutron widths Γη0 = Γηn/ε0½ are normally used. The mean values of the neutron resonance widths Γη correlate with the values of <D>. Each of these may differ by a factor of 103-104 for ...
The number of neutrons emitted from a nuclear reaction plays a crucial role in various fields, including nuclear theory, nuclear nonproliferation, nuclear energy and nuclear criticality safety. Accurate determination of neutron multiplicities requires the application of several corrections, with dead-time c...
The problem of modeling pulse profiles has been extensively studied in the literature. Studies have been done considering the Doppler effect, aberration; time delay [24] and fast rotation or stellar oblongation [25,26,27,28]. In particular, In [13] it was studied gravitational lensing propertie...
electron-based LDNS [62,64,65,66]. Utilizing LWFA to drive neutron sources, yields in the range of\(10^{7}\)to\(10^{8}\,{\hbox {n}}\,{\hbox {shot}}^{-1}\)have been reported [65]. The neutron yield per shot can be attributed to the relatively low electron number contained...
where Σ, the macroscopic cross-section, cm− 1; x, the path length (distance the neutron beam travels), cm; I0, the intensity of incident neutron beam, i.e., the number of particles passing across unit area in unit time, n cm− 2 s− 1; I, the intensity of the neutron be...
This links atomic nuclei to properties of neutron stars, thereby relating objects that differ in size by orders of magnitude. The nucleus 208Pb is of particular interest because it exhibits a simple structure and is experimentally accessible. However, computing such a heavy nucleus has been out ...
We should keep in mind that neutron cross sections can be specific and differ in value for certain reactions, such as proton (σρ)- and alpha particle (σα)-producing reactions, fission reactions (σf), or neutron capture cross sections (σc). The total neutron cross section (σtot or...
第一张:Neutron 是一个主从分布式应用程序,具有多个服务进程(e.g. neutron-server.service、l3_agent.service etc.),采用异步通讯模式。分为担任中央控制(接收北向 API 请求,控制逻辑,下达任务)的 Neutron Server 和担任地方执行者(执行任务,反馈结果)的 Agents,两者之间互为生产者/消费者模型,通过消息队列(MQ)进...
For this reason, taking the limit\nu \rightarrow \inftyin the dispersion relation (15) requires some care: the limit cannot simply be exchanged with the dispersion integral \begin{aligned}&\bar{T}^{\text {disp}}(\nu ,-Q^2) \nonumber \\&\quad =(Q^2+ 4\nu ^2)\!\int _0^{x...
To present these data, we create a unique index “C” for each possible neutron configuration based on the occupation numbers in the following way. In the sd–fp neutron space, we construct a seven digit number where each digit gives the number of particles in a particular orbital. For ...
