Duxbury has interpreted an atomic structure with the superscript element of a
particle as being in brackets
5#BF9#EE,FE9<#B16>
On page 26 of the guide it has grade 1 indicators before the subscript and
superscript symbol but Duxbury has not included those - should it have? I
notice that as far as superscripts in brackets are concerned the cell 5 is not
included as in the example on page 32 of the guide.
