Searching for Rare Decay Modes in the Reaction 238U+4He (40 MeV).

In the present paper we describe an experiment performed on the reaction 238U + 4He (40 MeV) using a two-arm TOF-E (time-of-flight vs. energy) spectrometer with micro- channel plate detectors and mosaics of PIN diodes. This experiment has aimed at searching for fine structures in the total kinetic energy vs. fragment mass (TKE - M) distributions of binary events, and disclosing rare ternary decay modes others than already known from ternary fission. Details of the procedures of data handling are briefly described as well. © 2007 American Institute of Physics [ABSTRACT FROM AUTHOR]
