Dear Mausumi,

Since each bin is normalised per GeV per Sr, you have to multiply by the bin size in energy (Multiplication by 3 as you said) and in Solid angle.

One easy way to calculate the solid angle bin size using polar angle bins in radians and assuming 2pi azimuthially is to multiply by 2*pi*(cos(èmin)-cos(èmax)).

Then if you sum all bins you should get the value close to 1.

Hope this helps

Kind regards

Lefteris

(See attached file: pb.inp)

Dear Anton lechner,
Thank you for your response.Would you please tell me that with which factor you multiplied each bin value considering proper solid angle? One factor is 3 for energy. I want to know the other factor for Sr. The input file is attached herewith.
With best regards.

Dear Mausumi,

Could you please send the entire input file? Why do you think the values are too high? Integrating the tab.lis file (considering the proper solid angle bins and the 3 GeV energy bin) I get almost one, i.e. almost one muon per primary is passing the surface between the specified regions in a 0-50 polar angle range wrt beam direction. This can also include primary particles.

Cheers, Anton

Dear all,
I have used USRYIELD scoring card to get angular distribution of muon escaping after transporting through a target and observed that in the tab.lis file for some angular bin around peak very high contribution like 29.0, 27.0 etc. although according to output file no. of secondary particle(muon) generated by primary is only 2.8%. I understand that the values I got are no.of particles per Gev per Sr per particle. Here the scoring is for muon while the incident beam is also muon. The tab.lis file is attached herewith. For USRYIELD card I use
USRYIELD 124 muon+ -57.0 Targ outtarg2 1.0 Yieang
USRYIELD 50.0 0.0 100.0 3.0 0.0 3.0&
With best regards
