The investigate intermediate mass fragment (IMF: 3{le}Z{le}20) emission from the neck region during fission, the reaction {sup 4}He + {sup 232}Th at E/A=50 MeV has been performed. An array of low threshhold, high resolution detector telescopes together with two position sensitive parallel plane gas detectors has been used in an exclusive experiment to measure both in-plane and out-of-plane neck emission of IMFs. In addition, the IMFs have been isotopically identified by the time-of-flight technique. The folding angle for binary events is compared to the folding angle measured for similar systems. The energy spectra of neck IMFs is compared to isotropically emitted IMFs. The angular distribution of IMFs relative to the fission axis will be presented.
