Ani Award

Frank M. Freimann Professor of Physics Ani Aprahamian was the keynote speaker at the Armenian American Medical Society's 35th Anniversary Gala held at Universal City, in California on November 20, 2021. Aprahamian serves the director of A. Alikhanyan National Science Laboratory of Armenia. At the gala Professor Aprahamian was also honored for her outstanding leadership and dedication in expanding the capacity of the scientific and healthcare sectors of the Republic of Armenia. “The Cryogen Center/Oxygen Generator project was one of the largest projects the AAMS has ever funded,” said Garni Barkhoudarian, MD, FAAP. “Professor Aprahamian was the person responsible for this project. Because of her, Armenia now has enough liquid oxygen for the entire country in all sectors for at least fifty years. We couldn’t think of a more deserving recipient.”…

Notre Dame researchers unlock clues to the production of isotopes in supernovae

The elements that make up our world were produced in various astrophysical environments. Some are produced in the cores of stars and some in violent cataclysmic explosions such as supernovae. Notre Dame researchers have now unlocked a key piece of a puzzle in understanding how some rare-earth nuclei, such as Mo and Ru, are produced in the cosmos. Among supernovae researchers, there has been a long-standing debate on whether the production of elements heavier than Cu is terminated by what is called the Ni-Cu cycle. This new experimental result hints that this is not actually the case, as it found that the (p,α) reaction that produces the isotope 56

Michael Wiescher, Freimann Professor of Physics published the biography “Arthur E. Haas – The Hidden Pioneer of Quantum Mechanics” at Springer. A German version is being published by the LIT Verlag in Vienna. Arthur E. Haas came to ND as a professor of physics in 1936 on the recommendation of Albert Einstein. At the time, he was a well known theoretical physicist who escaped from the growing dangers of fascism in Austria/Germany to the United States to build a new life.

NSF MRI awarded to Bardayan to conduct research on nuclear astrophysics

Author: Shelly Goethals

Professor Dan Bardayan received a Major Research Instrumentation (MRI) grant from the National Science Foundation to conduct research on nuclear astrophysics at the University of Notre Dame’s Nuclear Science Laboratory.

With the $505,000 grant to be matched with $217,000 from the University, Bardayan will develop a nuclear decay spectrometer called SABRE, the Silicon Array for Branching Ratio Experiments. SABRE will take advantage of the unique TriSol facility at the Nuclear Science Lab to measure proton and alpha branching ratios as small as one part in one-hundred thousand, which is characteristic of many important resonances of astrophysical interest.

Prof. Anna Simon will lead a project to develop a neutron irradiation station (NIS) at the Nuclear Science Laboratory at the University of Notre Dame. NIS will utilize a high-intensity proton beam from the 5U accelerator to produce a flux of neutrons at energies up to a few MeV via nuclear reactions on low-Z targets. First of its kind in the U.S., NIS will deliver monoenergetic neutron beams with intensities of the order of 108

deBoer offers new analysis of nuclear reaction data finds holes in a theory about the first stars

Uncertainty over First Stars

Stars are dutiful recyclers. The material used and discarded by one generation of stars is taken up and reused by the next. But that cycling process has trouble explaining the surprisingly high calcium concentrations in stars that formed early on. Astrophysicists have proposed that these old stars were seeded by a first generation that expired in “faint supernovae,” producing calcium but few other heavy elements. However, a new analysis of nuclear reaction measurements suggests that this model may not be so solid [1

Over the last few years CASPAR has driven forward with its for researching experimental plan. Work has continued through a global pandemic and underground blasting of nearby cavities. Students and faculty have pressed hard to complete crucial experiments before having to pause for extensive nearby excavations. Currently CASPAR has now been mothballed, but still has much to do.

Physics graduate students receive 2021 Kaneb Awards

Author: Shelly Goethals

Physics graduate students Kevin Lee (advised by Prof. Ani Aprahamian) and Sethupathy Subramanian (advised by Prof. Dinshaw Balasra) are the recipients of 2021 Outstanding Graduate Student Teaching Awards from the Kaneb Center. 

This award was created in 1999 to recognize graduate student instructors and TAs who demonstrate commitment to exceptional teaching in lectures, seminars, labs, and across the academic profession. The Graduate School and the Kaneb Center for Teaching and Learning present the award annually to TAs that are nominated by their departments. The award consists of a certificate from the Kaneb Center and Graduate School, a letter documenting the award for the graduate student’s file, a $100 honorarium, and an invitation to a formal event hosted by the Kaneb Center and the Graduate School.…
