On the time–modulation of the K–shell electron capture decay of H-like 140Pr ions produced by neutrino mass differences

چکیده

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 TEC = 7.06(8) sec and an amplitude aEC = 0.18(3). We show that this phenomenon can be explained by neutrino mass differences and derive a value for the difference of squared masses ∆m21 = m 2 2 − m 2 1 = 2.22(3) × 10 −4 eV. PACS: 12.15.Ff, 13.15.+g, 23.40.Bw, 26.65.+t

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 −...

The nuclear K–shell electron–capture (EC) and positron (β+) decay constants, λEC and λβ+ of H–like 140Pr and He–like 140Pr ions, measured recently in the ESR ion storage ring at GSI, were calculated using standard weak interaction theory. The calculated ratios R = λEC/λβ+ of the decay constants agree with the experimental values within an accuracy better than 3%. PACS: 12.15.Ff, 13.15.+g, 23.40...

Kinematics and Quantum Field Theory of the Neutrino Oscillations Observed in the Time-modulated Orbital Electron Capture Decay in an Ion Storage Ring

According to the recent experimental data of a GSI–experiment, the rate of the number of daughter ions Ce, produced by a nuclear K–shell electron capture (EC) of the H–like ion Pr, is modulated in time with a period Td = (7.06± 8) seconds. We explain this phenomenon by neutrino– flavour mixing and show that this can be understood within standard quantum field theory and derive a value for the s...

In a recent paper, oscillations observed in the electron capture probability were attributed to the mixing of neutrino mass eigenstates. This paper is shown to be in error in two respects. In a recent measurement[1] at GSI of the electron capture rate for hydrogen-like 140 P r ions, 140 P r 58+ → 140 Ce 58+ + ν (1) the decaying ions were found to have a non-exponential time dependence. The appr...

  A second-order approximation to the Faddeev-Watson-Lovelace treatment of the rearrangement channel is used in a three-body scattering cross sections. In this formalism, the Three-body wave function is expressed by three coupled integral equations, the Faddeev equations, which contian the two-body (off-shell) transition amplitudes, and proved the uniqueness of their solutions. This amplitude c...
