Separation of mass-overlapped time of flight-energy elastic recoil detection analysis data using Ryan and Jamieson's dynamic analysis method

Time of flight-energy (ToF-E) elastic recoil detection analysis (ERDA) data often contains mass signals with considerable overlap from adjacent isotop es in the mass-energy plane. An evaluation has been carried out of the suit ability of the dynamic analysis method proposed by Ryan and Jamieson to dec ompose elemental signals with overlapping mass. This method is shown to wor k very well on generated test data and the result when it was applied to ex perimental data appears quite promising. Very accurate mass calibration and lineshape determination was found to be a prerequisite for the application of the method. (C) 2001 Elsevier Science B.V. All rights reserved.
