J(ohannes) HANS D(aniel) JENSEN (1947-74)

Joint recipient with the U.S. physicists Maria Goeppert Mayer and Eugene P. Wigner of the Nobel Prize of Physics in 1963 for explaining the detailed characteristics of atomic nuclei.

According to their explanation known as the shell theory, a nucleus should be thought of not as a random motion of neutrons and protons about a point but rather as a structure of shells or spherical layers of differing radii, each of which is filled with neutrons and protons.

Jensen served on the faculty of the University of Hamburg from 1936 to 1941. He then joined the Institute of Technology in Hannover, leaving in 1949 to become professor at the University of Heidelberg.

Mayer, Wigner and he proposed their nuclear shell nodel in 1949. Jensen collaborated with Mayer in writing Elementary Theory of Nuclear Shell Structure (1955).
