Radiosotope data

Further data for naturally occuring isotopes of boron are listed separately. This table gives information about some radiosotopes of boron, their masses, their half-lives, their modes of decay, their nuclear spins, and their nuclear magnetic moments.

Isotope Mass Half-life Mode of decay Nuclear spin Nuclear magnetic moment
8B 8.024607 0.770 s EC to 8Be; EC + a to 4He; EC + 2 a to n 2 1.0355
9B 9.013329 8 x 10-19 s 2a to 1H; p to 8Be 3/2 1.8006
12B 12.014352 0.0202 s b- to 12C; b- + 3a to n 1 1.0031
13B 13.017780 0.0174 s b- to 13C 3/2 3.17778
