OPT-IN: Electromagnetic decay of the Σ*0 to Îγ

[Enzo DeSanctis]

I think the discussion of the physics output of the paper is too little. In particular, the last sentence of the abstract "This ratio is larger than most theoretical predictions by factors ranging from 1.5-3, but ...." is not commented in the text (see below).
 
- page 1, left column, par. 1,lines 11 and 13: why do you quote refs 5 and 6 of 1988 instead of more recent estimations for the valence quark, gluon and orbital momentum contributions to the nucleon spin?

- page 10, left column, par. 3,line 3: I think better writing "'...= 36.0 +/-5.0 MeV" for the branching ratio width,

At the end of this paragraph one should add, and discuss a bit longer, the last sentence of the abstract: "This ratio is larger than most theoretical predictions by factors ranging from 1.5-3."

- page 10, right column, par. 3,line 3: write "in part by the Italian Istituto Nazionale ..."
