Celebrating 75 Years of the Nuclear Shell Model and Maria Goeppert-Mayer

This year marks the 75th anniversary of the nuclear shell model, for which Maria Goeppert-Mayer and Hans Jensen won the Nobel Prize in Physics in 1963. In commemoration of this historic anniversary, Argonne National Laboratory and the University of Chicago hosted a symposium from July 19 to 21, 2024, dedicated to celebrating the legacy and enduring impact of the nuclear shell model and Maria Goeppert-Mayer's contributions to science. The symposium brought together researchers at all stages of their careers whose research descends from the development of the shell model. Topics presented ranged from historical overviews of 75 years of progress to ongoing research at the forefront of nuclear physics.

To commemorate the impact Maria Goeppert-Mayer has had on generations of women physicists, a session was dedicated to celebrating women and other underrepresented populations in physics. In an effort to continue her great legacy, discussions highlighted the accomplishments of women in physics as well as provided opportunities for dialogue about current challenges still faced by women and underrepresented minorities in physics and how we, as a community, can pursue a more equitable and diverse field.

11:00 AM Maria Goeppert Mayer – From Göttingen to the Nobel Prize in Physics

The talk will present an overview of Maria Goeppert-Mayer’s life and her accomplishments in physics. Being trained in quantum theory at the famous Göttingen school of Max Born, she became friends with many of the most influential physicists of the early 20th century. Albeit, as a woman and the wife of Joseph Mayer, she was considered unemployable in the United States, after her emigration from Germany. Nevertheless, she continued working as unpaid lecturer and made several substantial contributions to atomic and molecular physics. Collaborating with Edward Teller during World War II, she shifted her focus to nuclear physics, particularly to the field of nuclear astrophysics. Her research on the correlation between stellar abundances and the numbers of protons or neutrons in a nucleus, led her to the identification of magic numbers. Despite being dismissed by many physicists, her exploration into "numerology" ultimately led to the recognition of the shell structure of the nucleus. In 1963, she was honored with the Nobel Prize for her groundbreaking discovery.
