- W1990498723 abstract "The fine-structure interval $ensuremath{Delta}ensuremath{nu}$ of ground state ($n=1$) positronium has been measured to high precision, yielding $ensuremath{Delta}ensuremath{nu}=203.3849(12)$ GHz (6 ppm). Comparison with theory is at present limited by uncalculated terms of order ${ensuremath{alpha}}^{2}ensuremath{Delta}ensuremath{nu}$. Values for the linear coefficient of the fine-structure density shift, $aensuremath{equiv}(frac{1}{ensuremath{Delta}ensuremath{nu}})frac{ensuremath{partial}ensuremath{Delta}ensuremath{nu}}{ensuremath{partial}D}$, have been measured for positronium in nitrogen and the noble gases: $a({mathrm{N}}_{2})=(ensuremath{-}3.2ifmmodepmelsetextpmfi{}0.5)ifmmodetimeselsetexttimesfi{}{10}^{ensuremath{-}5}$ ${mathrm{atm}}^{ensuremath{-}1}$ (0ifmmode^circelsetextdegreefi{}C), $a(mathrm{He})=(+1.6ifmmodepmelsetextpmfi{}0.3)ifmmodetimeselsetexttimesfi{}{10}^{ensuremath{-}5}$ ${mathrm{atm}}^{ensuremath{-}1}$ (0ifmmode^circelsetextdegreefi{}C), $a(mathrm{Ne})=(ensuremath{-}1.9ifmmodepmelsetextpmfi{}0.4)ifmmodetimeselsetexttimesfi{}{10}^{ensuremath{-}5}$ ${mathrm{atm}}^{ensuremath{-}1}$ (0ifmmode^circelsetextdegreefi{}C), $a(mathrm{Ar})=(ensuremath{-}6.2ifmmodepmelsetextpmfi{}0.3)ifmmodetimeselsetexttimesfi{}{10}^{ensuremath{-}5}$ ${mathrm{atm}}^{ensuremath{-}1}$ (0ifmmode^circelsetextdegreefi{}C), $|a(mathrm{Kr})=(ensuremath{-}6.6ifmmodepmelsetextpmfi{}0.5)ifmmodetimeselsetexttimesfi{}{10}^{ensuremath{-}5}$ ${mathrm{atm}}^{ensuremath{-}1}$(0ifmmode^circelsetextdegreefi{}C), and $a(mathrm{Xe})=(ensuremath{-}7.3ifmmodepmelsetextpmfi{}1.7)ifmmodetimeselsetexttimesfi{}{10}^{ensuremath{-}5}$ ${mathrm{atm}}^{ensuremath{-}1}$ (0ifmmode^circelsetextdegreefi{}C). The positronium density shifts differ markedly from those of hydrogen." @default.
