We have performed the first high precision measurement of the coherent neutron scattering length of deuterium in a pure sample using neutron interferometry. We find b_nd = (6.665 +/- 0.004) fm in...
Magnetically Stabilized Luminescent Excitations in Hexagonal Boron Nitride (2001)
Huffman, P. R., Brome, C. R., Butterworth, J. S., Dzhosyuk, S. N., Golub, R., Lamoreaux, S. K., ...
Magnetically stabilized luminescence is observed in hexagonal boron nitride. The luminescence is induced by absorption of cold neutrons and is in the visible region. In the absence of a magnetic...
