¹⁹B has been observed in the bombardment of Be by 12 MeV/A ⁵⁶Fe ions (84MU27) and in the fragmentation of 44 MeV/A ⁴⁰Ar (88GU1A) and 55 MeV/A ⁴⁸Ca (91MU19). See also (89DE1X). The mass excess adopted by (93AU05) is 59.360 ± 0.400 MeV.

Shell model predictions for low-lying levels are discussed in (92WA22). See also (89PO1K, 90LO11).
