Richard Casten
American physicist

Richard Francis Casten (born November 1, 1941) is an American nuclear physicist known for his research in nuclear structure and radioactive nuclear beams. He is the D. Allan Bromley Professor Emeritus of Physics at Yale University, where he was the director of the Wright Nuclear Structure Laboratory from 1995 to 2008. He is also known for Casten's triangle, which was introduced in 1981.
Early life and education
Casten was born on November 1, 1941, in New York City. His father was a Jewish surgeon from New York and his mother was a Catholic homemaker. Casten was raised in Manhattan and attended the Quaker Friends Seminary, where he took chemistry classes and decided to pursue physics.
Casten enrolled at the College of the Holy Cross as a physics major and became a member of its honors program. The college's focus on a liberal arts education allowed him to take courses in history and philosophy, which he later recalled as having "an effect on my whole research career". He graduated from Holy Cross with a Bachelor of Science (B.S.), magna cum laude, in 1963.
After graduation, Casten pursued graduate studies at Yale University with the intention to study physics under D. Allan Bromley.

Why this record matters
The phrase “american physicist” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q2798144. VIAF identifies the subject as 73913777. The Library of Congress control number is n88013981. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1941, 1995, 2008 and 1981.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
