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

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 accelerating") OR ((((("particle accelerated") OR ("partially accelerated"))) OR ("particles accelerated")))))).
• Removing quotes may allow a broader search: (( particle accelerator ) or ((( particle accelerating ) or ((((( particle accelerated ) or ( partially accelerated ))) or ( particles accelerated )))))).
• Adding a wildcard symbol may retrieve word variants: (("particle accelerator") or ((("particle accelerating") or ((((("particle accelerated") or ("partially accelerated"))) or ("particles accelerated"))))))*.
