Appendix 4: Attachment Peaks and Cross Sections

CONTENTS

 

Attachment cross sections and peak energy of occurrence have been measured in a number of compounds that are considered before. The peak cross sections shown in the table are in units of 1.0 × 10−21 m2. Cross sections due to Modelli and Jones (2004) are normalized to 1.5 × 10−21 m2.
