Measured Ground-State Γ_cm for ¹¹O

Adopted value: 1.30 MeV (2019WE03)

Measured Mass Excess for ¹¹O

Adopted value:	47.65 MeV (From S2p = -4160 keV 2019WE03 and 2017WA10)
Deduced value:	46.70 ± 0.84 MeV (2012CH40)

2019WE03: ¹¹O(2p); measured decay products, E_p, I_p; deduced an invariant-mass spectrum, resonant state widths, two-nucleon density distributions. First observation of unbound ¹¹O.

2020WE08: ⁹Be(¹³O, ¹¹O), E = 69.5 MeV/nucleon; measured E_p, I_p, and invariant mass spectrum of ¹¹O fragments from (⁹C)2p-coin events with two-proton emission from two states in ¹¹O, longitudinal-momentum distributions. ¹¹O; deduced levels, S(2p) for ground state.
