Coordinated Research Projects

• CRPs are initiated by IAEA scientific experts following advice and

suggestions of “consultants” who participate in a Consultant’s

Meeting

• A proposal is formed and submitted for approval to the Committee

for Coordinated Research Activities

• After approval a Project Officer is designated and a call for

research contracts and agreement proposals follows

• Once the evaluation and selection of proposals is completed the

IAEA PO collaborates with Chief Scientific Investigators from the

different research institutes involved in order to develop and

manage the research programme

• Duration is normally 4 to 5 years

(15)

Coordinated Research Activities involving NSDD

• CRP on Reference Database for Beta-Delayed Neutron Emission:

• CRP on Nuclear Data for Charged-particle Monitor Reactions and Medical

Isotope Production:

International Network of Nuclear Structure and

Decay Data Evaluators (NSDD)

International Network of Data

Centres with the task of

evaluating nuclear structure and

decay properties of all nuclides

with a given mass chain number A

Evaluated data include:

disintegration energies, radiation

and transition probabilities, nuclear

level schemes, excitation energies,

half-lives, decay modes, spin-parity

values, magnetic and electric

multipole moments, and nuclear

band structure

The evaluated mass chains form

the Evaluated Nuclear Structure

Data File which is hosted and

managed at

http://www.nndc.bnl.gov/ensdf/

Masterfile available also at

http://www-nds.iaea.org

A-chain evaluations are published

in Nuclear Data Sheets

Unevaluated nuclear structure

and decay data are compiled in the

ENSDF format in the XUNDL

database

http://www.nndc.bnl.gov/xundl/

NDS IAEA coordinates the

Training Workshops

The primary objective of the ICTP-hosted

workshop was to familiarize nuclear physicists and

engineers from both developed and developing

countries with

• modern nuclear models;

• relevant experimental techniques;

• statistical analyses procedures to derive recommended

data sets;

• evaluation methodologies for nuclear structure and

decay data;

• international efforts to produce the Evaluated Nuclear

Structure Data File (ENSDF)

‘Pilot’ Workshop on Nuclear Structure and

Decay Data, Vienna, 18-22 November 2002

_{IAEA-ICTP Workshop on}

Nuclear Structure and Decay Data, 17-28

November 2003, Trieste, Italy

(23)

Workshops’ Program

• Participants are introduced to both the theory

and measurement of nuclear structure data,

statistical techniques, formats and procedures

and the use of computer codes to evaluate decay

data

• Detailed presentations are given by invited

lecturers, along with computer exercises and

workshop tasks

(24)

Workshops’ exercises

• Database search

• Running computer codes

• Evaluating individual nuclides

• Since 2012: mass chain evaluation

Ultimate goals

• Outreach: make nuclear structure & decay

data evaluation known to nuclear scientists

(ENSDF and derivative databases

(LiveChart, Nudat), NSR, analysis codes)

• Recruit new evaluators - maintain ENSDF

(27)

• Conception and implementation of ICTP-IAEA
