Phys. Rev. Lett. 83, 4955–4958 (1999)Giant Absorption Cross Section of Ultracold Neutrons in Gadolinium
See accompanying Physics Focus The transmission of ultracold neutrons through natural Gd and isotopic enriched 157Gd samples has been measured. Absorption cross sections in the order of 100 Mb have been identified. Here one touches a region where fluctuations of the physical parameters influence the result and can cause a basic deviation from the exponential attenuation law and where a purely imaginary interaction potential exists within the sample. © 1999 The American Physical Society URL:
