Calculations of the excitation function of 209 Bi (α, n) 212 At, 209 Bi (α, 2n) 211 At and 209 Bi (α, 3n) 210 At reactions have been focussed on alpha induced reaction. Energy ranges of alpha particles were taken into computations as 10 MeV to 70 MeV. The objective of this study is to compare the computed results with the experimental data existing in the literature for each reactions. The calculated 209Bi(α,xn) reaction cross-sections were computed using computer code COMPLET and were then compared with the experimental nuclear reaction data obtained from EXFOR library in the literature. This calculated data was analyzed and interpreted with tabular and graphical descriptions. Good agreement was found between the experimental and theoretical data. The results were briefly discussed within the text of this research work.

“…The Nuclear Reaction Data Centers (NRDC) in the International Atomic Nuclear Agency (IAEA) has accumulated the nuclear reaction data more than 50 years. The format of the data file is called EXFOR (Exchange FORmat) [11]. As the contribution to EXFOR from Japan, the nuclear reaction data centre (JCPRG) [12] has been compiling nuclear reaction data from published papers, in which experiments are done with the Japanese accelerators.…”

We propose a concept of a unified research management system (URMS) by utilizing services of cloud computing for the purpose of promoting the open science. In our concept, the important point of URMS is to combine different could services and to provide the services with an optimized combination for researchers according to the concerned scientific activity. We show the total concept and applications of URMS. Further, in order to illustrate our scenario for promoting the open science on URMS, we show an actual method for data clustering and discuss how the result from the clustering gives an impact to the promotion of the open science.

“…Nuclear reaction data underpin nuclear science and technology [1,2]. One of the most important works in nuclear physics is to measure the nuclear reactions and reduce the data uncertainties in order to achieve the accuracy requirements in fundamental research fields, such as nuclear astrophysics [3,4], and many application fields, such as transmutation of nuclear waste [5] and design of future nuclear reactors [6]. Since 1935, tens of thousands of experiments have been performed and hundreds of thousands of experimental data sets have been systematically collected to develop the experimental nuclear reaction databases, among which the most important and complete one is EXFOR [7].…”

Hundreds of thousands of experimental data sets of nuclear reactions have been systematically collected, and their number is still growing rapidly. The data and their correlations compose a complex system, which underpins nuclear science and technology. We model the nuclear reaction data as weighted evolving networks for the purpose of data verification and validation. The networks are employed to study the growing cross-section data of a neutron induced threshold reaction (n,2n) and photoneutron reaction. In the networks, the nodes are the historical data, and the weights of the links are the relative deviation between the data points. It is found that the networks exhibit small-world behavior, and their discovery processes are well described by the Heaps law. What makes the networks novel is the mapping relation between the network properties and the salient features of the database: the Heaps exponent corresponds to the exploration efficiency of the specific data set, the distribution of the edge-weights corresponds to the global uncertainty of the data set, and the mean node weight corresponds to the uncertainty of the individual data point. This new perspective to understand the database will be helpful for nuclear data analysis and compilation.
