Measurements of γ- and Neutron-Radiation Spectra in Nuclear Reactions with 3 He and 9 Be Ions

We present the measured spectra of γ and neutron radiation generated in the 9 Be( 3 He, p γ) 11 B and 9 Be( 3 He, n γ) 11 C nuclear reactions at an energy of 2.57 MeV of 3 He ions using a BC-501A organic detector and an HPGe semiconductor spectrometer. Line shapes of 6.9-MeV γ-transitions from the 9 Be( 3 He, n γ) 11 C reaction and 8.92-MeV transitions from the 9 Be( 3 He, p γ) 11 B reaction, measured at angles of 0°, 30°, 60°, 90°, and 120° have been determined. The angular distribution of protons emitted when populating the 8.92-MeV level of the 11 B nucleus in 9 Be( 3 He, p γ) 11 B reaction, as well as the energy distribution of neutrons in 9 Be( 3 He, n γ) 11 C reaction, have been reconstructed.
