In 1948, Mayer published a groundbreaking paper titled “On Closed Shells in Nuclei,” where she introduced the shell model of nuclear structure. This model explained how nucleons are arranged in discrete energy levels or “shells” within the nucleus, similar to the electron shells in an atom. Her work laid the foundation for understanding nuclear magic numbers, which are specific numbers of protons or neutrons that result in greater nuclear stability.
Nobel Prize in Physics
Maria Goeppert Mayer’s most significant recognition came in 1963 when she was jointly awarded the Nobel Prize in Physics alongside J. Hans D. Jensen for their discoveries concerning nuclear shell structure. She became only the second woman in history to receive the Nobel Prize in Physics, after Marie Curie, who won it in 1903.
The Nobel Committee’s recognition of Mayer’s work underscored the importance of her contributions to the field of nuclear physics. Her shell model provided a framework that not only explained existing experimental data but also guided further research and theoretical developments in nuclear physics for decades to come.
