Measurement of the 2s 2p2(4P) 3s 3P2 lifetime in N II by beam-foil-laser spectroscopy
نویسنده
چکیده
An accurate value for the radiative lifetime of the 2s 2p~(~P) 3s ~P~ level in N II has been obtained using the beam-foil-laser spectroscopy method. The result (T = 0.456 ± 0.020 ns ) is shorter than the beam-foil lifetime values reported previously for the 3s' ~P term. No theoretical value for the lifetime of this term is available at the present time.

متن کاملCollinear laser - beam — ion - beam measurement of the mean lifetime of the Ar II 4 p ' F 7 & 2 level
The mean lifetime w of the 4p' 'F7/2 level of Ar II has been measured using a variant of the collinear laser-beam —fast-ion-beam spectroscopy technique. Our variant requires no mechanical motion or laser frequency tuning. The result is ~=8.414+0.025 ns in agreement with an earlier, comparably precise, measurement based on a crossed laser —ion-beam technique. The result lies above all theoretica...
متن کاملDiagnostic Line Ratios for Highly Ionized Ions of the Beryllium Isoelectronic Sequence and a Comparison with Solar Observational Data
Observations of the relative line strengths of Beryllium like ions in a high temperature plasma can be used to derive the electron temperature and density of the emitting region through diagnostic line ratios [1,2]. However, to calculate such ratios reliably, accurate atomic data must be employed, especially for the electron impact excitation rates of the relevant transitions [3]. In this paper...
متن کاملNon-destructive depth profiling of the activated Ti-Zr-V Getter by means of excitation energy resolved photoelectron spectroscopy.
Non-evaporable Ti-Zr-V ternary getters (NEGs) were studied by means of excitation energy resolved photoelectron spectroscopy (ERXPS). We attempted a quantitative study of the in-depth redistribution of the NEG components during activation. The samples were prepared ex-situ by DC magnetron sputtering on a stainless-steel substrate. The ERXPS measurements were carried out at two incident photoele...
متن کاملMeasurement of the Neutron Lifetime by Counting Trapped Protons
We measured the neutron decay lifetime by counting in-beam neutron decay recoil protons trapped in a quasi-Penning trap. The absolute neutron beam fluence was measured by capture in a thin (6)LiF foil detector with known efficiency. The combination of these measurements gives the neutron lifetime: τ n = (886.8 ± 1.2 ± 3.2) s, where the first (second) uncertainty is statistical (systematic) in n...
