Abstract
A search was made for the occurrence of particle-stable tetraneutrons in the fast-deuteron-induced fission of uranium. This process is known to give a high yield of alphas and tritons. In order to deduce the presence of tetraneutrons, the following hypothetical reactions were investigated: , , , , and . No evidence for tetraneutrons was found. The upper limits of tetraneutron yields per alpha obtained from the above reactions are: 2×, 3×, 3×, 3×, 1×, and 1×, respectively. It seems reasonable to conclude from these results that the existence of tetraneutrons is most unlikely.
