Accessing data

There are three ways of accessing nuclear data with VuENSDF:

• Transfer via the Internet from a HTTP-server
• Data stored on a local disk or CD-ROM
• From the WWW, with VuENSDF working as a helper application for the browser

Data can be transferred by VuENSDF directly from the Isotopes Project Web server.

If the file CATALOG0.LOG (see VuENSDF files) is available, the user can select an available nuclide from the File, Select Nucleus menu:

The user first selects the database from the three options

As decay parent

ENSDF decay data sets by parent nucleus

As daughter or reaction product

ENSDF data sets by daughter nucleus (final nucleus)

With superdeformed bands

A continuously updated (by B Singh, McMaster) database with superdeformed band information

The user can then enter the nuclide specification (e.g. 60Co) in the text box. As the user starts writing the mass number of the nuclide, the program displays the existing entries in the list box below. The intended nuclide may be selected by double-clicking the corresponding entry in the list box.

A locally stored file in the ENSDF or ENSDF/2 format is opened using the File, Open local file... menu.

The whole of the ENSDF database is available in a convenient form on the Table of Isotopes CD-ROM. When this data structure is used, the nuclide can be selected with the command File, Select Nucleus.

Nuclear data files can be distributed on the Web in the ENSDF or ENSDF/2 format. The Web browser will recognize these file types, and launch VuENSDF provided

1. The server has been configured to transmit MIME type Application/ENSDF for ENSDF (extension .ENS) and ENSDF/2 (extension .ENX) files
2. The browser has been configured to launch VuENSDF for the MIME type Application/ENSDF with extensions .ENS and .ENX
