Project Motivation:
Project Motivation Up-to-date bb-decay and B(E2) evaluation
and compilation
Web Access & Dissemination
ENSDF evaluators & physicists need this
information
Utilization of my expertise in these subjects
B(E2) Nuclear Data Project I:
B(E2) Nuclear Data Project I B(E2) (http://www.nndc.bnl.gov/be2) was
launched 11/01/2005
Originally based on work of S. Raman
Over 200 nuclear data retrievals/month
Adopted retrievals - 72.6%
Experimental retrievals - 21.6%
Theoretical retrievals - 5.8%
B(E2) Nuclear Data Project II:
B(E2) Nuclear Data Project II Project is in a good shape
Nuclear physicists requests:
Weisskopf units were introduced in
addition to e2b2 and ps
Experimental methods are displayed
Database updates: 3-4 times a year
bb-decay Data Project I:
bb-decay Data Project I bb-decay (http://www.nndc.bnl.gov/bbdecay)
was launched 06/01/2006
Small scale (14 adopted & over 300
best experimental limits)
Duration of typical bb-decay measurement
is 2-3 years; database content grows slow
Collaboration with Viktor Tretyak from
INR, Kiev
Reliable source of data for ENSDF
bb-decay Data Project II:
bb-decay Data Project II NSR-based product; NSR was 95%
complete for bb-decay transitions, new NSR
entries were added
Lweight was used for adopted values
bb-decay transitions page based on data
from AMDC & NWC
Database updates 3-4 times a year
Conclusion & Outlook:
Conclusion & Outlook
Horizontal evaluations diversify NNDC
product offering
Proactive response to research & ENSDF
communities needs
Integration of B(E2) & bb-decay data with
NSR and ENSDF evaluations
FY 2009-2010: Produce B(E2) & bb-decay
evaluations for publication
