Ben Mottelson was the laureate of the Nobel Prize in nuclear physics in 1975 (together with Aage Bohr and James Rainwater) “for the discovery of the connection between collective motion and particle motion in atomic nuclei and the development of the theory of the structure of the atomic nucleus based on this connection”.
He was the co-author of the nuclear physics monographs (called sometime nuclear physics “bible”) – volume 1 “Nuclear Structure” and volume 2 “Nuclear Deformations”.

Ben Mottelson collaborated with many Polish physicists. He was also awarded with the Polish “Marian Smoluchowski Medal” in 1980.
