  Spectral yield of p+Be neutrons emitted by thick (stopping) beryllium target
bombarded by 16 MeV protons was estimated via extrapolation of literature data.
The spectrum was validated via multi-foil activation method and irradiation of
2N2222 transistors. The hardness parameter (NIEL scaling factor) for
displacement damage in bulk silicon was calculated and measured and kappa =
1.26 +- 0.1 was obtained.
