e/Di-positronium

Information
has gloss	eng: Di-positronium, or dipositronium, is a molecule consisting of two atoms of positronium. It was predicted to exist in 1946 by John Archibald Wheeler, and subsequently studied theoretically, but was not observed until 2007 in an experiment done by David Cassidy and Allen Mills at the University of California, Riverside. The researchers made the positronium molecules by firing intense bursts of positrons into a thin film of porous silica, which is the chemical name for the mineral quartz. Upon slowing down in silica, the positrons captured ordinary electrons to form positronium atoms. Within the silica, these were long lived enough to interact, forming molecular di-positronium.

Meaning
Russian
has gloss	rus: Молекуля́рный позитро́ний, дипозитро́ний, Ps2 — молекула, состоящая из двух атомов позитрония (то есть связанная система из двух электронов и двух позитронов).
lexicalization	rus: Молекулярный позитроний
Yue Chinese
has gloss	yue: 雙電子偶素係種唔穏定嘅分子，由兩粒正電子同埋兩粒電子組成。因為正電子同電子質量一樣，所以唔似氫分子，雙電子偶素唔係真係由兩粒電子偶素( )組成，而四粒基本粒子互相 dou 來 dou 去。研究員希望可藉研究渠揾到基本問題：「點解可見宇宙嘅正物質多過反物質咁多？」嘅一啲線索。
lexicalization	yue: 雙電子偶素
Chinese
has gloss	zho: 雙電子偶素是由兩個電子偶素所組成的分子，符號為Ps，是約翰·惠勒在1946年預言它的存在，隨後雙後電子偶素都只有理論上的研究。直到2007年才由再加州大學河濱分校的大衛·卡西迪和米爾斯發現它。他們主要把電子偶素撞擊極薄的矽晶片製成。.
