The masses of Be8, Be9 and B11, as determined from transmutation data

We(1) have investigated the gamma-ray spectrum resulting from the bombardment of Li by H(1). The spectrum is complicated but has a definite maximum at 16 mev = 0.0172 mass units. The intensity of the gamma-radiation increases rather suddenly when the bombarding voltage reaches 600 kv, and decreases again at higher voltage.
