Published<\/strong>: September 2025 <\/p>\n\n\n\n

Lead Author(s)<\/strong>: S. Coil<\/p>\n\n\n\n

The 14<\/sup>O(\u03b1,p)17<\/sup>F reaction triggers the \u03b1p process in X-ray bursts and dramatically impacts the observed light curve. The most important resonance in this reaction was studied via inelastic 17<\/sup>F+p scattering using 17<\/sup>F beams from the TriSol separator. The results were the subject of an Honor thesis by former Notre Dame undergraduate Sydney Coil and were recently published in Physical Review C. Learn more<\/a><\/p>\n\n\n\n

Bardayan Elected Director of ARUNA<\/strong><\/p>\n\n\n\n

\"\"<\/figure>
\n

Nuclear Science Laboratory (NSL) Director and Notre Dame Professor of Physics Dan Bardayan<\/a> was recently elected as the Director of the Association for Research at University Nuclear Accelerators (ARUNA<\/a>). ARUNA is an association of 13 university-based accelerator laboratories in the United States and the scientists performing nuclear research at them. ARUNA was founded in 2010, with the goals to optimize the use of university-based accelerator facilities, increase the opportunities for education around them, and document their scientific impact as part of the U.S. nuclear science enterprise. ARUNA members believe that the diversity of approaches represented by their laboratories is a critical asset for a field that is presently growing fast around the science opportunities offered by the Facility for Rare Isotope Beams (FRIB).<\/p>\n\n\n\n

The NSL is a founding member of ARUNA with a strong tradition in nuclear science research and is a national leader in the education of nuclear scientists. The NSL is the research base for 5-10% of nuclear science PhD students nationwide so it was natural for the NSL to take a turn in hosting ARUNA. ARUNA had been hosted by Florida State University since its founding in 2010.<\/p>\n\n\n\n

Scott Carmichael recently won the 2024 Nuclear Science Lab Browne Award and the Department of Physics and Astronomy Distinguished Research Award. Congratulations Scott!!<\/p>\n\n\n\n

Cornelius P. Browne served as the director for the Nuclear Structure Laboratory for nearly thirty years. Through his hard work and dedication, he steered the lab through the most successful period in its history. In honor of Dr. Browne this award is presented annually to an outstanding Nuclear Physics graduate student who has exemplified his work ethic.<\/p>\n\n\n\n

Scott was also awarded the departmental Distinguished Research Award. Carmichael was recognized for extraordinary efforts in commissioning a high-precision magnetic spectrometer at the Nuclear Science Laboratory and its subsequent use to elucidate radioisotope production in supernovae.<\/p>\n\n\n\n

Less than a year after its opening, the Facility for Rare Isotope Beams produced five never-before-seen isotopes for observation, a success that researchers say highlights the discovery potential of the facility. Nuclear Science Laboratory director Dan Bardayan<\/a> was interviewed for the American Physical Society News of the week about the discovery. He was quoted as saying \u201cOne of the fundamental observables of nuclear physics is whether a given nucleus exists or whether it simply falls apart into its constituents”.

Notre Dame undergraduate Sydney Coil has been awarded a 2023-2024 Charles Edison Fellowship. The Charles Edison Fellowship is a $1,500 fellowship that will be granted to two undergraduate students who are passionate about pursuing research, but have financial struggles. \u201cResearch is a vital element to an undergraduate science education. However, this process requires much time and effort, and many students cannot commit time to research due to financial circumstances and must rather have an on-campus job.\u201d says Daniel Pape, co-editor-in-chief of Scientia<\/em>. \u201cThe Edison Fellowship will give these students the opportunity to participate in research and make discoveries in their field of interest.\u201d <\/p>\n<\/div><\/div>\n\n\n\n

First Beam Transported to Enge Spectrograph<\/strong><\/p>\n\n\n\n

A milestone was reached in April 2023 as the first beam was transported to the Enge Spectrograph. A 14 MeV proton beam was tuned to the quartz viewer directly in front of the Enge target chamber with no noticeable loss in transmission. The quadrupole on the Enge beamline focused the beam to a spot roughly 3 mm wide as shown in the pictures below taken with the quadrupole off and on.<\/p>\n\n\n\n

Dan Bardayan was selected as a Fellow of the American Physical Society in November of 2022. Bardayan was nominated for his study of explosive astrophysical events with exotic beam measurements, and the development of unique experimental devices to perform such studies. He performs his experiments using transfer reactions at the TriSol magnetic spectrometer at the Notre Dame Nuclear Science Laboratory, the supersonic gas-jet target JENSA at Michigan State University, and the Gammasphere array at Argonne National Laboratory.<\/p>\n\n\n\n

No more than one-half of one percent of the APS membership are elected to the status of fellow each year. The fellowship program was created in 1921 for scientists in the physics community to recognize their peers\u2019 contributions to the field with original research, innovative applications, teaching and leadership.
