A neutron diffraction crystal spectrometer with a resolution of 13 microseconds per meter and monochromatic beam intensity up to 4 , 2 10 n/cm -sec in the range 0. 012-0. 400 ev has been constructed for 7 study of the activation cross section of Be as a function of energy in the thermal region. First preliminary results using ZnS(Ag) as a detector 7 7 suggest the possibility of a resonance for the Be (n, p)Li reaction in the region of 0. 025-0. 050 ev.
