Abstract
A method is provided for detecting resonant ultra sound (RUS) Spectroscopy peaks which is based upon taking the second derivative of the RUS spectrum. The second derivative provides a more sensitive analysis tool, and makes it possible to separate and distinguish peaks in the spectrum which are not readily discernable by other analyses of the spectrum. Analysis criteria such as cut off heights and Z-widths provide judgment criteria for identification of resonant peaks.
