Lifetime measurements of β-decaying highly charged ions have been performed in the experimental storage ring (CSRe) by applying the isochronous Schottky mass spectrometry. The fully ionized Cr49 and Fe53 ions were produced in projectile fragmentation of Ni58 primary beam and were stored in the CSRe tuned into the isochronous ion-optical mode. The new resonant Schottky detector was applied to monitor the intensities of stored uncooled Cr24+49 and Fe26+53 ions. The extracted half-lives T1/2(Cr24…

Frequency-selective harmonic retrieval for Schottky mass spectrometry.

A method based on the state space representation in the frequency domain to overcome the fine resolution limit of two closely spaced harmonics is proposed and greatly reduced the computational cost while still retaining superb accuracy.

Nuclear masses are the most fundamental of all nuclear properties, yet they can provide a wealth of knowledge, including information on astrophysical sites, constraints on existing theory, and

Electroweak Decays of Highly Charged Ions

In this contribution we review the present status of experimental studies of electroweak decays of highly charged ions. A particular focus will be given on the bound state beta decay measurement of

Denoising scheme based on singular-value decomposition for one-dimensional spectra and its application in precision storage-ring mass spectrometry.

The denoising effect of the proposed method is shown to be highly competitive among other existing nonparametric methods, including moving average, wavelet shrinkage, and total variation, as well as in precision storage-ring mass spectrometry.
