Energy values for some deuteron reactions with ¹⁰B, ¹¹B and ¹²C

With a 180° uniform field magnetic spectrometer, the following values for nuclear reaction energies have been obtained: ¹⁰B (dp) ¹¹B, Q = 9·227 MeV; ¹⁰B (dα) ⁸Be, Q = 17·829 MeV; ¹¹B (dα) ⁹Be, Q = 8·029 MeV; ¹¹B (dα) ⁹Be*, Q = 5·598 MeV; ¹²C (dp) ¹³C, Q = 2·720 MeV. From the ¹¹B (dα) ⁹Be and ¹¹B (dα) ⁹Be* reactions the energy of the first excited level in ⁹Be has been found to be 2·431 ± 0·006 MeV. A comparison with other results of comparable accuracy is given.
