Berkeley Experimenters Find New Lithium, Boron Isotopes

Recent measurements at Berkeley's Lawrence Radiation Laboratory show evidence for a surprisingly high degree of stability for some hitherto unknown isotopes of light elements including $Li11,$ $B14,$ and $B15.$ This work was reported by Arthur Poskanzer, Sam K. Cosper, Earl K. Hyde and Joseph Cerny in a paper in Phys. Rev. Letters 17, 1271 (1966), where data for a complete range of helium, beryllium, boron and carbon isotopes were presented.
