Perhaps you should try some spelling variations:
"particles accelerated" » "particles acceleration", "partially accelerated", "particle accelerators"
"particle accelerator" » "particle accelerators", "particle acceleration"
"particle acceleraton" » "particle acceleration", "particles acceleration", "particle accelerations"
"lattices accelerated" » "matrices accelerated", "devices accelerated", "lattices generated"
"particle accelerated" » "particle accelerators", "particle acceleration", "partially accelerated", "particle acceleratorsd", "particle accelerationd", "practice accelerated"
"particle accelerate" » "particle accelerators", "particle acceleration", "practice accelerate"

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 accelerate") OR ("particle acceleraton"))) OR ((("particles accelerated") OR ("lattices accelerated"))))) OR ("particle accelerated")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"particle accelerator\") or (((((((\"particle accelerate\") OR (\"particle acceleraton\"))) or (((\"particles accelerated\") or (\"lattices accelerated\"))))) or (\"particle accelerated\"))))".
• Removing quotes may allow a broader search: (( particle accelerator ) or ((((((( particle accelerate ) OR ( particle acceleraton ))) or ((( particles accelerated ) or ( lattices accelerated ))))) or ( particle accelerated )))).
• Adding a wildcard symbol may retrieve word variants: (("particle accelerator") or ((((((("particle accelerate") OR ("particle acceleraton"))) or ((("particles accelerated") or ("lattices accelerated"))))) or ("particle accelerated"))))*.
