Discovery of the krypton isotopes: 2010He02.
99Kr produced in Be(238U,f) using projectiles with E=345 Mev/nucleon. Identification of 99Kr made on the basis of magnetic ridigity, tine-of-flight, and energy loss.
Q-value: Esimated uncertainties (2017Wa10): 401 for Q(β-); 499 for s(n); 566 for s(p), and 641 for Q(α).
