摘要

Novel measurements of the neutron energy spectra of the9Be(d,n)10B reaction with a thick beryllium tar-get are performed using a fast neutron time-of-flight(TOF)spectrometer for the neutron emission angles 0 = 0° and 450,and the incident deuteron energies are 250 and 300 keV,respectively.The neutron contributions from the 9Be(d,n)10B reaction are distributed relatively independently for the ground state and the first,second,and third ex-cited states of10B.The branching ratios of the9Be(d,n)10B reaction for the different excited states of10B are obtained for the neutron emission angles 0 = 0° and 45°,and the incident deuteron energies are 250 and 300 keV,respect-ively.The branching ratio of the9Be(d,n)1B reaction for the third excited state decreases with increase in the incid-ent deuteron energy,and the branching ratios for the ground state and the second excited state increase with increase in the neutron emission angle.
