Ternary fission in the reaction {sup 4}He + {sup 232}Th at {ital E}{sub lab}=200 MeV has been observed. Intermediate mass fragments (IMF: 3{le}{ital Z}{le}8) with unique energy and angular distributions have been measured consistent with emission from the neck zone during fission. The widths of the energy spectra are relatively constant for neck fragments with {ital Z}{ge}4, suggesting little variability in the scission configurations. A linear dependence of {l_angle}{ital E}{r_angle} on {ital Z} is observed for the neck IMFs. The observed trend is compared with a Coulomb trajectory model. {copyright} {ital 1996 The American Physical Society.}
