#243 new physics

undestand strange distinction between large / small H2 in secondary rate

Reported by: Gary J. Ferland Owned by: nobody
Priority: major Milestone: h2star reintegration
Component: chemical network Version: trunk
Keywords: Cc:

Description (last modified by Gary J. Ferland)

understand following at mole_reactions.cpp:1350

if( h2.lgEnabled && h2.lgEvaluated && hmi.lgH2_Chemistry_BigH2 )
{
	return secondaries.x12tot*10.;
}
else
{
	return secondaries.x12tot*3.;
}

this affects cosmic ray excitation/dissociation??

should examine CR dominated model to see what effect this has on results.

The last change here was in r4748. Log message:

"branches/newmole/source - tripletdissoc variables unnecessary; kill them"

Before that it looked like this:

if( h2.lgH2ON  && h2.lgEvaluated && hmi.lgH2_Chemistry_BigH2 )
{
	return h2.tripletdissoc_H2g;
}
else
{
	return secondaries.x12tot*3.;
}

That code was added in r858, log message:

"Move further molecular reactions from H network to C network treatment."
