1986Po06,1986Pi11,1986De32: Rates for the most probable heavy-ion decays were calculated by 1986Po06 (14C, 8Be, 13C, 12C, 15C, 10Be, 15N and 18O emission), by 1986Pi11 (14C emission), and by 1986De32 (14C emission).
Q-value: Note: Current evaluation has used the following Q record $ 1194 7 4212 6 7170 50 6147 3 2003Au03
