Boron-10 is one of the two isotopes that make up natural boron deposits. The atomic nucleus consists of 5 neutrons and the element-specific 5 protons. The stable nuclide has a very high capture cross section (3837 barns) for low-energy thermal neutrons (< 0.5 MeV).

Boron (5 B) naturally occurs as isotopes 10 B and 11 B, the latter of which makes up about 80% of natural boron. There are 13 radioisotopes that have been discovered, with mass numbers from 7 to 21, all with short half-lives, the longest being that of 8 B, with a half-life of only 771.9(9) ms and 12 B with a half-life of 20.20(2) ms.

In nuclear industry boron is commonly used as a neutron absorber due to the high neutron cross-section of isotope 10 B. Its (n,alpha) reaction cross-section for thermal neutrons is about 3840 barns (for 0.025 eV neutron).

In boron: Properties, occurrence, and uses …mixture of two stable isotopes—boron-10 (19.9 percent) and boron-11 (80.1 percent); slight variations in this proportion produce a range of ±0.003 in the atomic weight. Both nuclei possess nuclear spin (rotation of the atomic nuclei); that of boron-10 has a value of 3 and that of boron-11, 3/2 ...
