Hans Jensen became to 25. June 1907 as a third child of the gardner Karl Friedrich Jensen and its Mrs. Helene Augusts Adolphine (born ohms) born. studied starting from 1926 at the university Hamburg and the Albert Ludwig university in Freiburg in mash gau Physics, mathematics, physical chemistry and philosophy. After its graduation in physics it remained as a scientific assistant in Hamburg and habilitierte 1936. He was appointed 1937 lecturer and 1941 the extraordinary professor at the technical university Hanover. it received 1949 from the Ruprecht Karl university Heidelberg a call to the tidy professor, whom it held up to its retirement 1969. During this time it had also several Gastprofessuren in the USA, among other things in Princeton and Berkeley, andwas since 1955 together with Otto Haxel co-editor of the magazine for physics.

Characteristic for humans Hans Jensen is the following Anektode:
As Jensen in the morning for the publication of the Nobelpreisverleihung by the Prime Minister of the country it was asked whether it one, said he has special desire immediately: yes, you can a stateless person student, who was driven out from the Iraq, who gives German nationality. The student received it. ([1]).


the first work Jensens, among other things its thesisand Habilitation, concerned themselves with refinements of the statistic Thomas Fermi model of the atomic shell, which substantial improvements brought. It begins end of the 1930er to be occupied with the atomic nucleus. He already speaks 1939 in a to a large extent empirical analysis of the atomic nuclei, their binding energyand frequentnesses for the first time of a shell model, without going however beyond the pure conceptualness. This formulation was however very vaguely held, since on the one hand the drop model of bore (1936) nuclear reactions very well described and the conception of coursesin the atomic nucleus no sense to make seemed. The further development became by the isolation of Germany in 2. World war retards, so that Jensen only end of the 1940er could again more intensively argue with the topic. Only 1948 succeeded to it by thoseAcceptance of a strong spin course coupling the break-through to an explanation of the magic numbers, whose meaning for the stability of the atomic nuclei admits already longer was - at the same time came in the USA Maria Goeppert Mayer on the same result, after her Enrico Fermithe possibility of a strong spin course coupling had suggested. In the consequence it came to one moves exchange between Jensen and Goeppert Mayer, which led to a nearly complete understanding of the characteristics of the lighter atomic nuclei.1955 published the two together in the book Elementary Theory OF Nuclear Shell Structure a detailed statement of the Verständisses of the atomic nuclei. For this achievement both 1963 were awarded one half of the Nobelpreises for physics in equal parts, the other half went at Eugene Wigner.
