Andrzej Sołtan
Andrzej Sołtan (25 October 1897 – 10 December 1959) was a Polish nuclear physicist. He also worked on spectroscopy in the band between far ultraviolet and X-rays. During his visit to Caltech in 1932–33, together with H. Richard Crane and Charles Christian Lauritsen, he discovered a method for producing neutron beams, by bombarding lithium or beryllium nuclei with accelerated deuterons. He was appointed professor at Warsaw University in 1947, a member of the Polish Academy of Sciences in 1952, and in 1955 he became the first director of the in Świerk, Otwock County near Warsaw, now known as the National Centre for Nuclear Research. He served as president of the Polish Physical Society between 1952 and 1955. He is buried (with his wife Marta, also a physicist) in the "Avenue of the Meritorious" of Warsaw's Powązki Cemetery. The institute where he worked was renamed the Soltan Institute of Nuclear Studies in 1982. References 1897 births 1959 deaths 20th-c ...

Nuclear Physics
Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions, in addition to the study of other forms of nuclear matter. Nuclear physics should not be confused with atomic physics, which studies the atom as a whole, including its electrons. Discoveries in nuclear physics have led to applications in many fields. This includes nuclear power, nuclear weapons, nuclear medicine and magnetic resonance imaging, industrial and agricultural isotopes, ion implantation in materials engineering, and radiocarbon dating in geology and archaeology. Such applications are studied in the field of nuclear engineering. Particle physics evolved out of nuclear physics and the two fields are typically taught in close association. Nuclear astrophysics, the application of nuclear physics to astrophysics, is crucial in explaining the inner workings of stars and the origin of the chemical elements.

Powązki Cemetery
Powązki Cemetery (; pl, Cmentarz Powązkowski), also known as Stare Powązki ( en, Old Powązki), is a historic necropolis located in Wola district, in the western part of Warsaw, Poland. It is the most famous cemetery in the city and one of the oldest, having been established in 1790. It is the burial place of many illustrious individuals from Polish history. Some are interred along the "Avenue of the Distinguished" - ''Aleja Zasłużonych'', created in 1925. It is estimated that over 1 million people are buried at Powązki.

Polish Academy Of Sciences
The Polish Academy of Sciences ( pl, Polska Akademia Nauk, PAN) is a Polish state-sponsored institution of higher learning. Headquartered in Warsaw, it is responsible for spearheading the development of science across the country by a society of distinguished scholars and a network of research institutes. It was established in 1951, during the early period of the Polish People's Republic following World War II. History The Polish Academy of Sciences is a Polish state-sponsored institution of higher learning, headquartered in Warsaw, that was established by the merger of earlier science societies, including the Polish Academy of Learning (''Polska Akademia Umiejętności'', abbreviated ''PAU''), with its seat in Kraków, and the Warsaw Society of Friends of Learning (Science), which had been founded in the late 18th century. The Polish Academy of Sciences functions as a learned society acting through an elected assembly of leading scholars and research institutions. The Academy h ...

Deuteron
Deuterium (or hydrogen-2, symbol or deuterium, also known as heavy hydrogen) is one of two stable isotopes of hydrogen (the other being protium, or hydrogen-1). The nucleus of a deuterium atom, called a deuteron, contains one proton and one neutron, whereas the far more common protium has no neutrons in the nucleus. Deuterium has a natural abundance in Earth's oceans of about one atom of deuterium among all atoms of hydrogen (see heavy water). Thus deuterium accounts for approximately 0.0156% by number (0.0312% by mass) of all the naturally occurring hydrogen in the oceans, while protium accounts for more than 99.98%. The abundance of deuterium changes slightly from one kind of natural water to another (see Vienna Standard Mean Ocean Water). (Tritium is yet another hydrogen isotope, with two neutrons, that is far more rare and is radioactive.) The name ''deuterium'' is derived from the Greek , meaning "second", to denote the two particles composing the nucleus. Deuteri ...
