Neutral particle weapon

From Memory Alpha, the free Star Trek reference.

Neutral particle weapons were a type of ship-mounted weapon used by the Talarians in the 24th century.

The weapon was no match for Federation starships, like the USS Enterprise-D.

The Captain of the Talarian warship Q'Maire, Endar, powered up the weapons of his ship, neutral particle weapons, X-ray lasers and merculite rocket in order to "convince" the crew of the Enterprise to return his adopted son, Jono. (TNG: "Suddenly Human")
