摘要
In this work, the neutron radiation field at Heavy Ion Research Facility in Lanzhou （HIRFL） was investigated. Total neutron yields, spectra and angular distributions in the bombardment of various thick targets by 12C and ^18O ions with energies up to 75 MeV/u were obtained using the activation method. The neutron dose equivalent rates of 60 MeV/u ^18O on various thick targets at different angles were measured with a modified A-B remmeter. Our results are compared with those of other reports.
