Editing Antiproton (section)

=== Possible applications ===
Antiprotons have been shown within laboratory experiments to have the potential to treat certain cancers, in a similar method currently used for [[Particle therapy|ion (proton) therapy]].<ref>{{cite journal|url=http://www.engr.psu.edu/antimatter/Papers/pbar_med.pdf |title=Antiproton portable traps and medical applications |date=1997 |url-status=dead |archive-url=https://web.archive.org/web/20110822150631/http://www.engr.psu.edu/antimatter/Papers/pbar_med.pdf |archive-date=2011-08-22 |doi=10.1023/A:1012653416870 |last1=Lewis |first1=R.A. |last2=Smith |first2=G.A. |last3=Howe |first3=S.D. |journal=Hyperfine Interactions |volume=109 |pages=155–164 }}</ref> The primary difference between antiproton therapy and proton therapy is that following ion energy deposition the antiproton annihilates, depositing additional energy in the cancerous region.
