Its large size has also made it the candidate of choice for atom-by-atom manipulation, including the development of a single atom switch in 1996 and the precise placement of 35 atoms on a nickel crystal to spell "IBM".
At 2.4 billion barns, the 135 isotope of this element has by far the highest neutron absorption cross-section, so much so that older nuclear reactors have to wait for enough of it to decay to prevent a "precluded startup," but fortunately this wait is less than a day.

FTP, identify this noble gas discovered in 1898 by Ramsey and Travers, with atomic number 54 and symbol Xe.
