DOI: 10.1103/physreva.100.062504

Abstract: We report the first measurement of the radium ion's $7p$ ${}^{2}P_{3/2}^o$ state branching fractions and improved theoretical calculations. With a single laser-cooled radium-226 ion we measure the $P_{3/2}$ branching fractions to the $7s$ ${}^{2}S_{1/2}$ ground… read more here.

Published in 2021 at "Physical Review A"

DOI: 10.1103/physreva.103.032814

Abstract: The present paper reports on a merged-beam experiment on mutual neutralization between ${\mathrm{Na}}^{+}$ and ${\mathrm{D}}^{\ensuremath{-}}$. For this experiment, we have used the DESIREE ion-beams storage-ring facility. The reaction products are detected using a position- and… read more here.

DOI: 10.1103/physrevd.101.111901

Abstract: We analyze the quasi-two-body decays B+→π+ρ(770,1450)0→π+K+K- in the perturbative QCD approach. The results in this work do not support that large branching fractions contributed by the resonances ρ(770,1450)0 in the B±→π±K+K- decays. The virtual contribution… read more here.
