Abstract
Beryllium enriched to 5% in has been extracted from neutron-irradiated carbon, and has been used for targets in nuclear spectroscopy. The cross section for the production of via deuteron bombardment of has been measured from 0.67 to 3.0 MeV, and the production cross section of has been measured from 2.3 to 12 MeV. The yield for both reactions varies smoothly with bombarding energy, and no resonance in is seen. From magnetic spectroscopy of the reaction, the mass excess of is found to be 20.174±0.007 MeV (=0) and the excitation energy of the first excited level to be 318 ± 7 keV. The angular distribution of protons populating the 318-keV level is an pattern, implying .
