Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.

Thank you for your answer.
I tried both QGSP_BIC and QBBC but none of them lead to satisfactory results. Since I'm running my simulation with incident alpha of 3 TeV I shouldn't have problems with the Coulomb barrier. By the way, what do you call Shielding Physics list. Is it the name of a particular physics list ?
