19Na (72AJ02)


(See the Isobar Diagram for 19Na)

A study of the reaction 24Mg(p, 6He)19Na at Ep = 54.7 MeV reveals a group of 6He particles corresponding to a state in 19Na with M - A = 12.974 ± 0.070 MeV. It is presumed to be the ground state of 19Na, although the close proximity of the second T = 3/2 state in 19O from the first (96 keV), does not permit a definite assignment. If it is assumed that 19Na(0) has M - A = 12.974 ± 0.070 MeV, then 19Na is unbound with respect to decay into 18Ne + p by 0.366 ± 0.070 MeV (CE69). The mass excess of 19Na is calculated to be 12.965 ± 0.025 MeV, using a seniority scheme, and 12.968 ± 0.025 MeV, using a supermultiplet scheme [both these values were calculated assuming that the lowest Jπ = 3/2+; T = 3/2 state in 19Na is 0.096 MeV above the Jπ = 5/2+; T = 3/2 state, as in 19O] (HA69H).
