number of antineutrinos at the far hall is R = 0.944± 0.007(stat) ± 0.003(syst). A rate-only analysis finds<br />

sin 2 2θ13 = 0.089± 0.010(stat) ± 0.005(syst) in a three-neutrino framework. The experiments will continue<br />

for several years and more precise neutrino mixing angle θ13 will be given in the future.<br />

Developments of the EXFOR Database: Possible New Formats<br />

IAEA Nuclear Data Section<br />

The EXFOR database is a collection of experimental nuclear reaction data, maintained by the IAEA<br />

on behalf of the International Network of Nuclear Reaction Data Centres (NRDC). The format for the<br />

storage of such data was first described in 1969 and while there have been many incremental changes<br />

over the years so that the format is now capable of containing a very wide range of measurement results,<br />

there is a growing realisation that a major change is required. Consequently the IAEA NDS organised<br />

a Consultant’s Meeting on “Further Development of EXFOR” in March 2012. This was an opportunity<br />

for a range of international experts to discuss ways of improving EXFOR and while this focussed on new<br />

formats there was also discussion on ways of storing new data, new output formats and software tools<br />

such as editors. This paper will discuss recent and proposed changes to enable new quantities to be stored<br />

(such as coincidence measurements and covariances), the range of output formats available (such as C4 and<br />

X4+) which make interaction with the data more user friendly and the possible use of XML to modernise<br />

the database.<br />

Nuclear Structure Databases and Services at NNDC<br />

The primary mission of the <strong>National</strong> Nuclear Data Center (NNDC) at <strong>Brookhaven</strong> <strong>National</strong> <strong>Laboratory</strong><br />

(BNL) is to compile, evaluate, and disseminate nuclear structure, radioactive decay, and nuclear reaction<br />

data. This presentation will confine to nuclear structure-related activities only at NNDC. The principal<br />

effort at NNDC in this regard is devoted to maintain, update, and disseminate the following databases:<br />

the Evaluated Nuclear Structure Data File (ENSDF), the Nuclear Science Reference (NSR) file, and the<br />

Experimental Nuclear Data List (XUNDL). NSR is a bibliographic database which includes most nuclear<br />

physics experimental as well as theoretical papers. The relevant articles are keyworded for easy search and<br />

assigned unique key numbers for easy reference. The references from the file can be retrieved by various<br />

criteria via user-friendly query program. The ENSDF is a collection of useful evaluated properties of all<br />

known nuclides with their supporting experimental data. The XUNDL provides unevaluated experimental<br />

data in ENSDF format as soon as the paper appears in literature. The retrievals from ENSDF and XUNDL<br />

are provided through NNDC web service in various different formats. Many of these databases are best<br />

accessed via NuDat, a state-of-art retrieval database using the latest data and technology. The evaluations<br />

in ENSDF are published in the Elsevier journal Nuclear Data Sheets. These together with compilations<br />
