Los Alamos National Laboratory Theoretical Nuclear Physics Scientist (Scientist 2 / 3) in Los Alamos, New Mexico

Vacancy Name: IRC71404


Job Title Theoretical Nuclear Physics Scientist (Scientist 2 / 3)

Location Los Alamos, NM, US

Organization Name T-2 / Nuclear & Particle Physics, Astrophysics & Cosmology

What You Will Do

This position will be filled at either the Scientist 2 or Scientist 3 level, depending on the skills of the selected candidate. Additional job responsibilities (outlined below) will be assigned if the candidate is hired at the higher level.

The Nuclear Data Team in the Nuclear Physics, Particle Physics, Astrophysics and Cosmology (T-2) group in the Theoretical Division at Los Alamos National Laboratory (LANL) is seeking outstanding candidates for a staff scientist position to work on applied nuclear physics. The successful applicant will be expected to develop nuclear models and codes, and using those tools to produce evaluated nuclear data, as are present in the ENDF U.S. nuclear data library. A strong background and an established record of high-quality research in fission theory, nuclear structure and/or nuclear reaction theories, and/or nuclear data evaluations are required. This staff position will engage with the nuclear data evaluation and benchmarking communities through the U.S. Cross Section Evaluation Working Group (CSEWG), U.S. Nuclear Data Program (USNDP), and other working groups, and support the release of future versions of the ENDF U.S. evaluated nuclear data library. The Nuclear Data Team has close ties with experimental groups at the Los Alamos Neutron Science Center (LANSCE) and the Nuclear and Radiochemistry Group (C-NR), with the X-Computational Physics (XCP) Division, which the new hire would be expected to reinforce. The successful candidate will be expected to publish in high-quality technical journals, demonstrate excellent communication skills, and work effectively across organizational boundaries within the Laboratory, and with the international nuclear data community. The ability to obtain a Q clearance is required.

Scientist 2 ($87,800 - $144,800)

The successful candidate will:

  • Experience in theoretical and computational modeling of nuclear reaction and/or structure physics

  • Publish research in leading scientific journals

  • Strong programming skills

  • Work both independently and in a team environment to solve problems in support of Laboratory missions

Scientist 3 ($96,600 - $161,300)

In addition to the duties outlined above, the (higher level title) will be required to:

  • Lead and guide interdisciplinary teams consist of nuclear theory, experiment, and application, to develop new theoretical and computational tools for prediction of nuclear reactions

  • Produce essential nuclear data and provide them for Laboratory users

  • Recruit and mentor postdocs and junior staff

  • Provide leadership in preparing proposals that guide future research directions of the group

What You Need

Minimum Job Requirements:

  • Understanding nuclear reaction models and codes, and evaluated nuclear data files

  • Demonstrated ability to write computer programs in modern languages

  • Demonstrated ability to communicate effectively, both written and orally

Additional Job Requirements for (Scientist 3):

In addition to the Job Requirements outlined above, qualification at the Scientist 3 level requ i res:

  • 5+ years of relevant R&D experience

  • Experience in developing and writing theoretical nuclear physics models and codes

  • Outstanding track record of sustained scientific accomplishment with commensurate publication

  • International reputation in relevant area of expertise as demonstrated by publications, invited presentations, professional service and/or professional honors

Desired Skills: Familiarity with neutron interaction with nuclei and nuclear fission

Education Required: Ph.D in Nuclear Physics or Engineering

Notes to Applicants:

  • A cover letter addressing each of the required skills is suggested along with a resume

  • For questions, contact: Toshihiko Kawano at
