Spins of low-energy neutron resonances in 235U

Abstract The spins of 15 resonances in the 235 U slow neutron cross section lying in the neutron energy range between 0.1 and 15 eV were determined by measuring the transmission of polarized monoenergetic neutrons through a target in which the 235 U nuclei were polarized. The magnetic moment of 235 U is concluded to be negative.
