Perhaps you should try some spelling variations:
"particles acceleratedd" » "particles acceleration", "particle accelerators", "particle acceleration", "particles accelerationd", "partially acceleratedd", "lattices acceleratedd"
"particles accelerated" » "particles acceleration", "partially accelerated", "lattices accelerated"
"particle accelerator" » "particle accelerators", "particle acceleration"
"particle accelerate" » "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 accelerate") OR ("particles accelerated"))) OR ("particles acceleratedd"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"particle accelerator\") or (((((\"particle accelerate\") OR (\"particles accelerated\"))) or (\"particles acceleratedd\"))))*".
• Removing quotes may allow a broader search: (( particle accelerator ) or ((((( particle accelerate ) OR ( particles accelerated ))) or ( particles acceleratedd ))))*.
