Both platforms were created by Elsevier's so it is inconceivable that they are the same. Scopus is a bibliographic database and Sciverse integrates several research platforms.
I think that journals that mention SciVerse indexing refer to outdated info that is no longer relevant (just like for example Scirus and Microsoft Academic Search that no longer exists). The journal “Journal of X Ray Science and Technology” is Scopus indexed. You can check that here: https://www.scopus.com/sources.uri?zone=TopNavBar&origin=searchbasic So, the indexing info (https://www.iospress.com/catalog/journals/journal-of-x-ray-science-and-technology ) of this journal is correct. For the most updated version you can go to https://www.scopus.com and scroll down and click on “Scopus source list” in order to download the latest Excel file.
Best regards.
PS. Perhaps someone can ‘proof’ the opposite, but I strongly believe that SciVerse no longer exists (the link http://www.info.sciverse.com/scopus/ is dead) and Scopus nowhere refer to this ‘service’ anymore (https://www.elsevier.com/solutions/scopus ). It used to be an integrated platform to analyze citation info etc. I guess it is now simply integrated in Scopus (and only accessible with a (paid) license).
