8 collimations 109-209-209-209 we obtained a wavevector resolution of dQ=Q ˆ 0:0020. Inelastic neutron scattering. A 50-g powder sample was sealed with He exchange gas in a thin-walled aluminium can for the inelastic neutronscattering experiments at the NIST centre for neutron research. For energy transfers ,40 meV we used a direct geometry time-of̄ight (TOF) spectrometer in the neutron energy g...

Advances in neutron-based radiation therapies such as Boron Neutron Capture Therapy (BNCT) pushes towards the development of new neutron spectrometers, whose key features are to be their practicability, reliability, energy resolution and detection range. The ACSpect is a novel spectrometer based on two-stages monolithic silicon telescope detector coupled an organic scintillator working active c...

We have detected the optical counterpart to the nearby isolated neutron star RX J1605.3+3249 using observations from the Space Telescope Imaging Spectrometer aboard the Hubble Space Telescope. The counterpart, with m50CCD = 26.84± 0.07 mag and very blue colors, lies close to the ROSAT HRI error circle and within the Chandra error circle. The spectrum is consistent with a Rayleigh-Jeans tail who...
