On the time–modulation of the K–shell electron capture decay of H-like 140Pr ions produced by neutrino–flavour mixing
According to recent experimental data at GSI, the rate of the number of daughter ions Ce, produced by the nuclear K–shell electron capture (EC) decay of the H–like ion Pr, is modulated in time with a period Td = 7.06(8) sec and an amplitude aEC = 0.18(3). We show that this phenomenon can be explained by neutrino– flavour mixing and derive a value for the quadratic mass difference ∆m21 = m 2 2 −...

متن کاملEvidence for CP Violation in Time-IntegratedD ! h hþ Decay Rates
R. Aaij et al.* (LHCb Collaboration) (Received 6 December 2011; published 12 March 2012; publisher error corrected 12 March 2012) A search for time-integrated CP violation in D ! h hþ (h 1⁄4 K, ) decays is presented using 0:62 fb 1 of data collected by LHCb in 2011. The flavor of the charm meson is determined by the charge of the slow pion in the D þ ! D þ and D ! D decay chains. The difference...
متن کاملModulation of Anxiety-Like Behavior in Sildenafil Citrate-Treated Mice Placed in an Elevated Plus-Maze
Introduction: Sildenafil, a phosphodiesterase-5 (PDE5) inhibitor, may have various effects on the central nervous system via the nitric oxide (NO)-cyclic guanosine monophosphate (cGMP) pathway. Preclinical studies have shown the controversial effect of sildenafil on anxiety-like behavior in animals. This study was undertaken to investigate the acute effect of sildenafil on anxiety-like behavior...
متن کاملELECTRON-ION RECOMBINATION RATE COEFFICIENTS AND PHOTOIONIZATION CROSS SECTIONS FOR ASTROPHYSICALLY ABUNDANT ELEMENTS. IX. Ni xxvi AND Ni xxvii FOR ULTRAVIOLET AND X-RAY MODELING
The inverse processes of photoionization and electron-ion recombination of (h þ Ni xxvi$ Ni xxvii þ e) and (h þ Ni xxvii$ Ni xxviiiþ e) are studied using the unified method for the total recombination. The method subsumes both the radiative and dielectronic recombination processes and enables self-consistent sets of results for photoionization and electron-ion recombination by using the same wa...
