A thick beryllium layer was bombarded with alpha particles from polonium coated on a platinum disk 3 mm in diameter. The neutron spectrum of the reaction Be/sup 9/ ( alpha ,n) C/sup 12/ was measured from the recoil protons in nuclear photoemulsions (100 microns). 12,000 tracks were processed. The neutron spectrum disclosed maxima at energies of 1.3, 4.4. and 6.9 Mev. The maximum energy of the neutrons was 10.7 Mev. The energy distribution of the neutrons obtained is in considerable disagreement with existing data. In the author's opinion, this may be explained both by the greater statistical error of his measurements compared with other works, as well as by the unique geometry he employs.
