Title: Improved electron-beam ion-trap lifetime measurement of the Ne[sup 8+] 1s2sthinsp[sup 3]S[sub 1] level

Abstract

An earlier electron-beam ion-trap (EBIT) lifetime measurement of the Ne[sup 8+] 1s2s hthinsp;[sup 3]S[sub 1] level has been improved upon, reducing the uncertainties to less than the scatter in the existing theoretical calculations. The new result, 91.7[plus minus]0.4 [mu]s, agrees with the previous value, but is more precise by a factor of 4. The new value distinguishes among theoretical values, as agreement is obtained only with those calculations that employ [open quotes]exact[close quotes] nonrelativistic or relativistic wave functions. Routes to measurements with even higher accuracy are discussed. [copyright] [ital 1999] [ital The American Physical Society]
