Albert Ghiorso
Albert Ghiorso (born July 15, 1915 in Vallejo , California , † December 26, 2010 in Berkeley , California) was an American nuclear physicist .
Ghiorso earned a Bachelor of Science degree in electrical engineering in 1937 and was involved in the construction of Geiger counters. Because of these activities, he was appointed to the Manhattan Project team and later worked in Glenn Seaborg's group on research into transuranic elements (atomic number greater than 92).
Ghiorso was - among others - involved in the discovery of the transuranic elements with ordinal numbers 95 to 106:
- Americium around 1945 (Element 95)
- Curium 1944 (element 96)
- Berkelium 1949 (Element 97)
- Californium 1950 (Element 98)
- Einsteinium 1952 (Element 99)
- Fermium 1953 (element 100)
- Mendelevium 1955 (Element 101)
- Nobelium 1958/1959 (element 102)
- Lawrencium 1961 (Element 103)
- Rutherfordium 1969 (element 104) - a first synthesis of the element took place in 1964 at the Soviet nuclear research center near Dubna
- Dubnium (since 1997, previouslycalled Hahnium ) 1970 (element 105) - a first synthesis of the element took place in 1967 also at the Soviet nuclear research center Dubna, close to Moscow
- Seaborgium 1974 (Element 106)
In 1972 Ghiorso was elected to the American Academy of Arts and Sciences . In 1973 he received the American Chemical Society Award for Nuclear Applications in Chemistry , and in 2004 he received the Lifetime Achievement Award from the Radiochemistry Society. In 1986 he became a Fellow of the American Physical Society .
In his honor the element 118, Oganesson , Ghiorsium should be named. After it became known that a colleague had allegedly falsified the measurement data on which the discovery was based, the proposed name had to be withdrawn.
