Source-derived summary

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.

Editorial summary

Begin with the source’s own compact description: “Richard Casten” is american physicist. The dossier treats that line as a proposition to test through Richard, Casten and American, not as a finished interpretation.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1941, 1995, 2008, 1981—that can be checked directly. The linked authority record independently contributes the date 1941-11-01. For this dossier, Richard, Casten and American is the immediate research focus.
Editorial analysis

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.

Evidence profile

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.

Critical limits

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.

How to read it
