Neutron irradiation of heavy-fermion superconductors
Physical Review B, 1988Upon neutron irradiation by ${10}^{18}$ neutrons/${\mathrm{cm}}^{2}$, Eg1 MeV, the superconducting transition temperatures of ${\mathrm{UBe}}_{13}$ and ${\mathrm{UPt}}_{3}$ fall by 40% and 60%, respectively---a factor of 3 more rapid than found in any other superconductor.

Paramagnetic defects in neutron-irradiated GaP
Journal of Applied Physics, 1992Aiming at a better understanding of intrinsic defects in III-V compounds, we reinvestigate fast-neutron-irradiated GaP. The surprising result is the observation of a similar spectrum, formerly ascribed to Asi-related defects in GaAs. Annealing experiments suggest this spectrum involves an impurity, probably boron.

Plasma Protein Synthesis Following Neutron Irradiation
Radiation Research, 1967The incorporation of14 C-glycine into the plasma proteins of rats at 3, 10, and 30 days following whole-body irradiation with fast neutrons has been measured. Only at 3 days postirradiation did the specific activity of the proteins from the irradiated rats exceed that of their pair-fed controls.

Neutron Irradiation of Human Melanoma Cells
Pigment Cell Research, 1989The biological characteristics and in vitro radiosensitivity of melanoma cells to thermal neutrons were investigated as a guide to the effectiveness of boron neutron capture therapy. Plateau phase cultures of three human malignant melanoma‐established cell lines were examined for cell density at confluence, doubling time, cell cycle parameters ...

The International Journal of Applied Radiation and Isotopes, 1981
Abstract Topaz single crystals, on neutron irradiation, change their colour to pale pink, pink and reddish pink, as the duration of irradiation increases. The hardness of the irradiated crystal increases with the increase in the total dosage. The increase in hardness caused due to irradiation is reduced to a considerable extent by heat treatment ...

A neutron collimator for animal irradiations
Medical Physics, 1974A collimator for exposures of portions of small animals to 15‐MeV neutrons is described. The radiation field behind the collimator was mapped with various detectors that determined dose, neutron spectra, and fluxes.

Positron lifetimes for neutron-irradiated C $_{60}$
Applied Physics A: Materials Science & Processing, 1995The neutron-irradiation effects on C60 fullerite powder were studied by positron lifetime spectroscopy. Below 0.5 ns, a single lifetime of 382±1 ps was found for the unirradiated annealed sample and two components were resolved after neutron irradiation with a dose of 2×1016 n/cm2. Possible origins of these components are briefly discussed.

Magnetic relaxation in neutron-irradiated iron
Physica Status Solidi (a), 1973Measurements of the magnetic after-effect, observed as a time decrease of the initial susceptibility, have been made on high purity iron after irradiation with fast neutrons to a dose of 9.8 × 1018n cm−2 at 45°C. Below 0°C strong relaxation peaks were observed at −68 and −13°C, in good agreement with earlier work, and attributed to the reorientation of
