Novel measurements of the neutron energy spectra of the ⁹Be(d,n)¹⁰B reaction with a thick beryllium target are performed using a fast neutron time-of-flight (TOF) spectrometer for the neutron emission angles $\theta=0^\circ$ and $45^\circ$ , 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 excited states of ¹⁰B. The branching ratios of the ⁹Be(d,n)¹⁰B reaction for the different excited states of ¹⁰B are obtained for the neutron emission angles $\theta=0^\circ$ and $45^\circ$ , and the incident deuteron energies are 250 and 300 keV, respectively. The branching ratio of the ⁹Be(d,n)¹⁰B reaction for the third excited state decreases with increase in the incident deuteron energy, and the branching ratios for the ground state and the second excited state increase with increase in the neutron emission angle.
