Abstract:
By using 28MeV/u 18O beam,an on-line melting lead target equipment and 4π-ΔEβ-γcoincident technique,the relative cross section ratios and absolute cross sections of neutron-rich nuclides 205—208Hg have been measured. The production cross section of 209Hg is extrapolated.The cross section of 207Hg produced by-2p +1n from target decreases suddenly,which may be explained by change of reaction Q value.
