Wladyslaw Swiatecki (physicist)

from Wikipedia, the free encyclopedia

Wladyslaw Jerzy Swiatecki , called Wladek, (* 1926 in Poland as Władysław Świątecki ; † September 30, 2009 in Berkeley (California) ) is a Polish theoretical physicist.

life and work

Swiatecki grew up in Lublin and fled to England with his parents in 1939. He studied at Imperial College London with a bachelor's degree in physics in 1945 and in mathematics in 1946 and received his doctorate in 1950 under Rudolf Peierls at the University of Birmingham ( The surface energy of nuclei ). As a post-doctoral student he was at the Niels Bohr Institute in Copenhagen from 1950 to 1953, at the Gustav Werner Institute in Uppsala from 1953 to 1956 and at the University of Aarhus in 1956/57 . He then went to the Lawrence Berkeley National Laboratory (LBNL). He officially retired there in 1991, but continued researching there until his death.

He developed precise theories for calculating the potential thresholds for nuclear fission and other dynamic phenomena (such as deformations, nuclear fusion), which also made it possible to predict islands of stability for superheavy elements. In formulas for the core masses, he developed the so-called microscopic-macroscopic method, a combination of the droplet model with the shell model. He also developed a theory of the single-particle damping of nuclear collisions, which had application to the optimal center of mass energy in heavy ion collisions. He worked closely with the heavy elements group at the LNBL and undertook theoretical studies on heavy ion collisions such as those investigated at the LNBL's Bevalac from the 1970s. Among other things, he was involved in: Spectator (audience) concept, Abrasion Ablation Model. He was also interested in chaos theory in cores and the influence of symmetries on core shapes.

In 1990 he received the Marian Smoluchowski Medal . In 1973 he became a member of the Royal Danish Academy of Sciences. In 2000 he received an honorary doctorate from the Jagiellonian University in Cracow and was a member of the Polska Akademia Umiejętności in Cracow.

He is not to be confused with the eponymous inventor of a bomb-dropping construction, Władysław Świątecki (1895–1944).
