Our paper on the radium ion's P_{3/2} branching fractions was published in PRA. We did this work in collaboration with theorists Marianna Safronova and Sergey Porsev who made calculations of key matrix elements in the system, from which they obtain the P_{3/2} branching fractions. The branching fractions tell you on average which of the three states (the S_{1/2} ground state, and the D_{3/2} and D_{5/2} metastable states) are populated when the radium ion decays from the excited P_{3/2} state. This first measurement of these branching fractions is necessary for a basic understanding of the system, such as calculating the dipole matrix elements that connect the electronic states. It was gratifying to see a nice agreement between measurements and theory in this work.
