Robert Smolańczuk (born in Olecko, Poland) is a Polish theoretical physicist.
He later visited Lawrence Berkeley National Laboratory (LBNL) as a Fulbright Fellow between 1998 and 2000.
He predicted in late 1998[1] that a lead-and-krypton collision technique could produce the element oganesson, at that time considered impossible by most scientists involved in heavy-element research.
This was experimentally attempted at LBNL in 1999 and appeared to have been successful, but an investigation determined that the data had been fabricated by Victor Ninov.
Smolańczuk received the Nitchke Award in 2000 for developing a phenomenological model of synthesis of superheavy nuclei.
