| الوصف: | Direct mass measurements of 78 Kr projectile fragments have been performed in the recently commissioned storage ring CSRe employing the isochronous mass spectrometry method. A new data-analysis technique has been developed to correct the drifts in the revolution frequencies caused by instabilities of the magnetic fields in the CSRe, thus yielding a mass resolving power of R = m / Δ m ≈ 1.7 × 10 5 (sigma). Masses for 45 V, 47 Cr, 49 Mn and 51 Fe nuclei are determined with a relative mass precision of δ m / m ≈ 2 × 10 − 7 (sigma) which is an improvement by a factor of ∼ 2 compared to the literature values. |
