Neutrons from the proton bombardment of 6Li,7Li,9Be,
11B, and 18O
1.5 m diameter graphite sphere neutron detector.
Eight BF3 counters were used.
The numerical information of this paper also had been
gained and renormalized from the published figures by
Liskien for his evaluation. See F0004 (AND,15,57,1975)
