Institute of Technology. Together they would publish Energy Levels of Light Nuclei, a compilation of the field's best yearly research regarding nuclear structure and decay of nuclei with an atomic mass number A from 5 to 20. Since 1973 Ajzenberg published them herself. Eventually Ajzenberg would publish 26 of these papers, primarily in the journal Nuclear Physics, until 1990. They have been called "the nuclear scientists' bible." Following graduation, Ajzenberg was a lecturer at Smith College and a visiting fellow at the Massachusetts Institute of Technology. She was hired as an assistant professor of physics at Boston University, but the dean lowered her salary 15 percent when he learned Ajzenberg was a woman. Ajzenberg refused the position until the initial salary was restored. While at Boston University, she met Harvard University physicist Walter Selove and they married in December 1955. One of her graduate students was Gloria Lubkin, who graduated in 1957 with an MA in Nuclear Physics, and would later become the first female editor in chief of Physics Today. In 2013, Lubkin wrote Ajzenberg's obituary as her final story for the magazine. In 1962, using the bubble chamber at the Brookhaven National Laboratory, Selove discovered a meson he named the fayon (f2) after her. Ajzenberg-Selove and her husband were honored with a symposium about their work at the University of Pennsylvania in 2005. Selove died in 2010. In the 1960s, she worked at Haverford College, where she was the first full-time female faculty member. In 1970, Ajzenberg-Selove began teaching at the University of Pennsylvania, where Selove had taught since 1957. In 1972, she applied for one of three tenured positions there. She was not hired; the reasons cited were age and "inadequate research publications". Ajzenberg-Selove was only 46, had a citation count higher than everyone in the physics department except for Nobel laureate J. Robert Schrieffer, and was Nuclear Physics Section chair of the American Physical Society. She filed complaints with the Equal Employment Opportunity Commission and the Pennsylvania Human Relations Commission and in 1973 the University of Pennsylvania was ordered to give her a tenured professorship. She became only the second female professor in the university's School of Arts and Sciences. Publications In 1994, she published a memoir, A Matter of Choices: Memoirs of a Female Physicist.
