We restarted the work with radium 224 and now 6 years later we have results on the two low-lying D state lifetimes: https://t.co/Oxqf23f6UB

[Jayich Lab @Jayich_Lab]

In 2019 we started a collaboration with Marianna Safronova and Sergey Porsev to measure and calculate the metastable D state lifetimes of the radium ion.

We started with radium 226 and found interesting systematics associated with its decay to the relatively long-lived radon 222, which caused collisional shifts. At some point we even figured out we could load strontium ions with the background ionizing radiation.

Spectroscopy of the Ra-224 ion's important transitions. With this and our photoionization paper, Ra-224 (3.6 d half-life) is straightforward to use. https://t.co/nipubbloGo

Our first work with radium-225 is on the arXiv: https://t.co/tYtlTfiRFS laser cooling, hyperfine measurements, & SPAM.

[Jayich Lab @Jayich_Lab]

Yesterday in the lab the radium team realized Rabi flopping of the electron spin in the hyperfine ground state of a radium-225 ion. A microwave drove the electron's orientation between up and down. This is a plot from the lab notebook.

Neat that Guido van Rossum commented on an issue raised by Ganden: https://t.co/qHwKlZXT5a

Radium-224 has a 3.6 day half-life. We've been laser cooling Ra-224 ions in a sealed system since February. Persistence and careful work to see the first ions got us through a bottleneck, opening many opportunities, starting with this paper posted today: https://t.co/J1zySfu6q9

Our perspective piece on the latest measurement (and best limit) of the electron's permanent electric dipole moment came out yesterday: https://t.co/0bHcWohNlt
