Dear Karolina,

if you get a null distribution, this means that you have no statistics
(run many more primaries) or(/and) that your setup/input has some major
issues.
Use USRYIELD and select lab polar angle as first differential quantity and
kinetic energy as second (filtering) differential quantity (taking a wide
scoring gamma energy interval not to filter them out), ask - as it should
always be done with USRYIELD! - for double differential *yield*
(d2N/dx1dx2).
In case, send your input

Kind regards

Francesco

I tried to use USRYIELD and USRBDX as you suggested but I'm getting a flat distribution with all values equal zero or energy distribution. On the manual or presentations I didn't find suitable example. How do I get angular distribution?
