![]() When fully zoomed in, the nucleus' name, ground state half-life, Nucleus' cell and mouseover tooltips become more detailed. Zooming in reveals additional information within each When zoomed in, only a fraction of the chart is displayed. When fully zoomed out, the entire chart is displayed and the magic numbers (8, 20, 28, 50, 82 and The chart can display multiple levels of zoom using the scroll wheel, pinch gestures on touch devices, or the National Nuclear Data Center, information extracted from the NuDat database,Įxperimentally known nuclei are represented by a cell in the chart with the number of neutrons on the horizontalĪxis and the number of protons on the vertical axis. (tables and plots) in their work, reports, presentations, articles and books.įor those interested in quoting NuDat, we suggest Users should feel free to use the information from NuDat Users should be aware that NuDat contents change often as new data is incorporated. Users are urged to promptly reportĪny problems encountered when using NuDat. Of the data or the absence of errors in the application. We cannot, however, guarantee the accuracy recommended valuesįollowing a careful analysis of the available data. NuDat contains evaluated nuclear data - i.e. To all BNL web products, including NuDat. Java to accomplish its programming tasks. Structured Query Language (SQL) commandsĪre issued to access the database. Total number of Beta- and EC/Beta+ transitionsĪ relational database is used to store the data. Total number of gamma rays with known multipolarity Total number of levels with known spin and parity Total number of levels with known half-life NuDat is periodically updated to reflect changes inĪ table with a brief statistics on NuDat can be found below: The management of ENSDF resides at the NNDC. Physicists from around the world contribute to this effort. The sections of NuDat related to levels, gammas and decayĪre obtained from the Evaluated Nuclear Structure Data File ( ENSDF). Second one for decay-related information, andĪ third one for searching the Nuclear Wallet Cards file.Ī description of the search capabilities can be found byĬlicking the help link at the top of each form, or by following the following links:Ī brief explanation of the many terms used in NuDat ![]() There are three different search forms: one for levels and gammas, a A sidebar menu for quick scrolling up and down the page.csv" button that saves the table onto the user's computer A "Band Transitions" table, which appears if the nuclide has bands of energy levels.Three more tables of information - "Additional Gamma Data," "Additional Level Data," and "Additional.Checkboxes for showing/hiding each of the columns in the main table.Version of the Adopted Levels & Gammas table is now available for every nuclide. To use it, select one observable property each for the X and Y axes, then click 'Plot.' This tool allows users to plot observable nuclear properties for a range of nuclides. Clickable data points and an interactive color key to highlight the currently selected line.A zoom button to zoom to a selected area.The 1-D neutron and proton plots have been updated with: A rescale button to set the color key to the minimum and maximum values of the current chart view.Export nuclear structure and nuclear decay data as a:.Filter by ground and isomeric state properties.An expandable menu with additional controls and features.A movable current nucleus display with a search field and a zoom to slider.Smooth pan and zoom using intuitive gestures.The interactive chart of nuclides has been updated with: NuDat 2 was implemented by Alejandro Sonzogni at the National Nuclear Data Center (NNDC) In tables, level schemes and an interactive chart of nuclides. The information provided by NuDat can be displayed (energy, intensity, multipolarity, coincidences), radiation informationįollowing nuclear decay (energy, intensity, dose), and neutron-induced reaction dataįrom the ENDF/B-VII.0 library (thermal cross section and fission yields). Nuclear level properties (energy, half-life, spin-parity), gamma-ray information Using NuDat, it is possible to search for Nuclear structure, nuclear decay and some neutron-induced nuclear reaction information. It provides an interface between web users and several databases containing To search and plot nuclear structure and nuclear decay data interactively. NuDat is a web application that allows users
