Jensen, Johannes Hans Daniel, 1907–73, German physicist, Ph.D. Univ. of Hamburg, 1932. Jensen was a professor at the Technical Univ. of Hanover from 1941 to 1949, when he joined the faculty at Heidelberg. He was named professor emeritus in 1969. Jensen received the 1963 Nobel Prize in Physics with Maria Goeppert-Mayer and Eugene Wigner. Jensen and Goeppert-Mayer were cited for their discoveries concerning nuclear shell structure. Working independently, and later collaboratively, the two explained the stability of certain isotopes as a result of the arrangement of the protons and neutrons in the nucleus.
