Abstract

The spectral lines of the 478 keV prompt γ-ray from7*Li produced in the10B(n, α)7*Li reaction were measured for a silicon wafer coated with a thin boron layer using neutron beams. The shapes of the Doppler broadened lines were found to depend greatly on the angle between the measurement axis and the boron layer surface. The angular dependence was interpreted according to whether the energetic7*Li ions are ejected into air or into the substance in the forward or backward recoil of7*Li to the γ-ray detector.

  6. Unpublished data: We simulated the spectral lines withD=0.1, 0.01, and 0.001·1012s−1, using Eqs (1) to (6). Any difference in their shapes was not found apparently. It was also revealed in our simulation that the line shape changes sensitively only in the range of 0.1<D/λ<10, corresponding roughly to 1·1012s−1<D<100·1012s−1.
