We have measured the angular distributions and production cross sections for the products of the reaction of 859-MeV ($E_{\text{c.m.}}=461.9\hspace{0.5em}\text{MeV}$) ${}^{160}\mathrm{Gd}$ with ${}^{186}\mathrm{W}$. We detected fragments that stopped in the 5.775 mg/cm${}^2$ target as well as fragments emerging at $9^{°}$–${17}^{°}$, ${17}^{°}$–${90}^{°}$, and ${90}^{°}$–${180}^{°}$. We also made a chemical separation of the Pb isotopes formed in this reaction. An unusually large yield of trans-target reaction products near $Z=79$ was observed. We compare these observations with the recent predictions of Zagrebaev and Greiner for this reaction.
