[8] At Rutgers she has been a major member of the nuclear physics research group working on the tandem Van de Graaff accelerator, as well as a condensed-matter physicist, performing experiments using the Mössbauer effect, by which she investigated the electronic structure of magnetic materials.
[9][10] According to the 'Contributions of 20th Century Women to Physics' (CWP) Project of the UCLA entry on Koller, Koller was a pioneer in several areas of nuclear and condensed matter physics, including the first identification of the double gamma decay of the observationally stable but theoretically unstable 40Ca isotope to the ground state: a 0+ → 0+ transition;[11] the observation of the interplay of single particle and collective motions in nuclei;[12] and the description of a broad range of nuclear electromagnetic transitions in the rare earth region using a simple relation based on constant gyromagnetic ratios for nucleon pairs.
At Rutgers, Koller served in the administration of the university as the associate dean for sciences of the faculty of arts and sciences from 1992 to 1996, and was active in the American Physical Society (APS), serving on many national committees, as well as chair of the 2,500-member APS Nuclear Physics Division.
Koller is a strong supporter of women in science and has contributed a significant amount of research to the physics community internationally.
[4][8] While in graduate school at Columbia University in 1956, Noemie Benczer married fellow physics student Earl Leonard Koller.
[2][7] When Noemie took up her position at Rutgers, Earl was hired at the Stevens Institute of Technology in Hoboken, NJ.
