Notes. For the current RCI calculations length τl and velocity τυ forms are both displayed. In Cols. 6 and 7, the predicted lifetimes from MCHF-BP and BSCI calculations are, respectively, given in length form. The last column contains available lifetimes from experimental measurements, together with their uncertainties.
