Perhaps you should try some spelling variations:
"particle accelerations" » "particle accelerators", "particles acceleration", "particle concentrations", "particle acceleratorss"
"particle acceleration" » "particle accelerators"
"particles accelerated" » "particles acceleration", "lattices accelerated", "particle accelerators"
"partially accelerated" » "partially correlated", "partially integrated", "naturally accelerate"
"particle accelerator" » "particle accelerators"
"particle acceleraton" » "particles acceleration", "pareticle acceleration", "particle accelerators"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("particle accelerator") OR ((((("particle accelerations") OR ("particle acceleration"))) OR ((((("particles accelerated") OR ("partially accelerated"))) OR ("particle acceleraton")))))).
• Removing quotes may allow a broader search: (( particle accelerator ) or ((((( particle accelerations ) or ( particle acceleration ))) or ((((( particles accelerated ) or ( partially accelerated ))) or ( particle acceleraton )))))).
• Adding a wildcard symbol may retrieve word variants: (("particle accelerator") or ((((("particle accelerations") or ("particle acceleration"))) or ((((("particles accelerated") or ("partially accelerated"))) or ("particle acceleraton"))))))*.
