Assistant Scientist

Job ID 2918Date posted 11/19/2021

Brookhaven National Laboratory ( delivers discovery science and transformative technology to power and secure the nation’s future. Brookhaven Lab is a multidisciplinary laboratory with seven Nobel Prize-winning discoveries, 37 R&D 100 Awards, and more than 70 years of pioneering research. The Lab is primarily supported by the U.S. Department of Energy’s (DOE) Office of Science. Brookhaven Science Associates (BSA) operates and manages the Laboratory for DOE. BSA is a partnership between Battelle and The Research Foundation for the State University of New York on behalf of Stony Brook University. BSA salutes our veterans and active military members with careers that leverage the skills and unique experience they gained while serving our country. Our organization fully supports service members transitioning from active duty to civilian life and pledge’s our commitment to actively hire veterans of the U.S. Armed Forces. Military personnel who have been formally trained or have relevant experience obtained while in service may meet educational requirements and are encouraged to apply for job opportunities at BSA.

Organizational Overview

Brookhaven National Laboratory’s Nuclear Science and Technology Department conducts research and development related to nuclear technologies (reactors and accelerator-driven systems), reliability and risk assessment, and advanced modeling techniques for reactor simulation and energy systems.

The Department serves as a resource in these and related areas to support the missions of the Department of Energy (DOE), the Nuclear Regulatory Commission (NRC), and other national and international organizations. With a world-class staff of professionals with expertise in a broad range of areas related to the design and analyses of commercial, research and advanced nuclear systems, Brookhaven’s capabilities and facilities are also available to support and execute experiments in support of these missions. The National Nuclear Data Center (NNDC), a part of BNL’s Nuclear Science and Technology Department, is the lead unit of the US Nuclear Data Program (USNDP), whose mission is to provide current, accurate, authoritative data for workers in pure and applied areas of nuclear science and engineering. This is accomplished primarily through the compilation, evaluation, dissemination, and archiving of extensive nuclear datasets. USNDP also addresses gaps in the data, through targeted experimental studies and the use of theoretical models.

The NNDC is responsible for the Nuclear Science Reference (NSR), eXperimental Unevaluated Nuclear Data List (XUNDL), Evaluated Nuclear Structure Data File (ENSDF) and Evaluated Nuclear Data File (ENDF) libraries, as well as the Nuclear Data Sheets journal.   The NNDC is also the main contributor to the EXFOR library.  Web dissemination of these libraries is also one of the main activities at the NNDC.

In addition to the libraries and web efforts, the NNDC staff are involved in research relating to nuclear structure, nuclear reactions, nuclear astrophysics and nuclear reactor antineutrinos.

Nuclear Data activities started at BNL in 1952 under the Brookhaven Neutron Cross Section Compilation Group, changed to the Sigma Center in 1961, which became the National Neutron Cross Section Center in 1967 and finally NNDC in 1977, providing a more than 65 years of nuclear data expertise to nuclear science and technology professionals.

Position Description

The National Nuclear Data Center has an opening for an Assistant Scientist in nuclear structure evaluations and research. In this role, you will be expected to work on all aspects of the Evaluated Nuclear Structure Data File (ENSDF), the world-wide resource for nuclear structure and decay data, including the development of a new format and ancillary codes and compilation and evaluation of nuclear structure and decay data. You will also be expected to participate in experimental research aligned with ENSDF priorities, including a new, in-house laboratory being built for decay spectroscopy experiments. This position has a high level of interaction with an international and multicultural scientific community.

Essential Duties and Responsibilities

  • Perform a critical review of experimental data and provide recommended values to be included in the ENSDF database.
  • Extract and vet data from recent publications for inclusion in the XUNDL database.
  • Assist in the development of the next generation ENSDF format and develop applications that employ Machine Learning techniques to compile and evaluate nuclear data.  
  • Participate in and analyze experiments related to the ENSDF database.

Position Requirements

Required Knowledge, Skills, and Abilities:

  • PhD in experimental low-energy nuclear physics
  • Minimum of at least two years of full-time relevant post-doctoral experience
