Abstract
Using the ISOLDE on-line isotope separator at CERN to produce sources of , , , , and , and using polycarbonate track-recording films sensitive to energetic carbon nuclei but not to alpha particles, we have discovered two new cases of the rare decay mode—in and . Our results for branching ratios, , relative to alpha decay are for and , ; for , ; for , ; for , .
