Theoretical determination of (d, n) and (d, 2n) excitation functions of some structural fusion materials irradiated by deuterons

Measurements of neutron energy spectra of 9Be(d,n)10B reaction with a thick beryllium target *

“…Accelerator neutron sources are widely used in neutron physics and neutron applications, owing to the high neutron yield, good controllability, compactness, and nonproliferation capability [1][2][3][4][5][6][7][8][9]. Typically, in exothermic nuclear reactions, deuterons and tritons are bombarded with deuterium ions, producing fusion neutrons by the 2 H(d,n) 3 He (D-D) and 3 H(d,n) 4 He (D-T) reactions, and deuterium ions bombard beryllium, producing neutrons by the 9 Be(d,n) 10 B (D-Be) reaction for low energy ions at keV.…”

“…36 MeV, but there are four wellknown excitation states of 10 B [10,11]. With increasing energy of deuterium ions, several many-body reactions ( 9 Be(d,2n) 9 B ( = −4.1 MeV), 9 Be(d,np) 9 Be ( = −2.2 MeV), and 9 Be(d,2np) 8 Be ( = −3.8 MeV)) markedly enhance the neutron yield and extend the neutron energy spectrum. However, measurements of the neutron energy spectra, angular distribution, and integrated yields for the 9 Be(d,xn) reaction have been scarce, and the existing studies mainly focus on the deuterium ion energies from a few MeV to tens of MeV .…”
