Figure 14
To make the data for Figure 14, follow these steps to run multi-zone
calculations. First, however, disable 18F(n,α)15N by creating a reaction rate
modification view. In particular, uncomment and edit the example view in
projects/nucnet-tools-code/data_pub/simple_snII__zone.xml:
<optional_properties>
...
<property
name = "nuclide xpath"
tag1 = "rate modification view"
tag2 = "1"
></property>
<property
name = "reaction xpath"
tag1 = "rate modification view"
tag2 = "1"
>[reactant = 'f18' and reactant = 'n' and product = 'n15']</property>
<property
name = "factor"
tag1 = "rate modification view"
tag2 = "1"
>0.</property>
</optional_properties>
This causes the reaction rates for any nuclei and reactions satisfying the XPath
expressions to be multiplied by the factor zero during the calculation. Now run the
calculation as you did here.
Next, disable 18F(n,p)18O with the following reaction rate modification view XPath
expressions:
<optional_properties>
...
<property
name = "nuclide xpath"
tag1 = "rate modification view"
tag2 = "1"
></property>
<property
name = "reaction xpath"
tag1 = "rate modification view"
tag2 = "1"
>[reactant = 'f18' and reactant = 'n' and product = 'o18']</property>
<property
name = "factor"
tag1 = "rate modification view"
tag2 = "1"
>0.</property>
</optional_properties>
Run the calculation again as you did here.
Finally, disable all 18F neutron captures by editing the reaction rate modification
view XPath expressions as follows:
<optional_properties>
...
<property
name = "nuclide xpath"
tag1 = "rate modification view"
tag2 = "1"
></property>
<property
name = "reaction xpath"
tag1 = "rate modification view"
tag2 = "1"
>[reactant = 'f18' and reactant = 'n']</property>
<property
name = "factor"
tag1 = "rate modification view"
tag2 = "1"
>0.</property>
</optional_properties>
Run the multi-zone calculation. Once all three calculations are complete, make the
plot as you did here.
