Neon-19 is a radioisotope of the chemical element neon, which has 9 neutrons in its atomic nucleus in addition to the element-specific 10 protons; the sum of the number of these atomic nucleus building blocks results in a mass number of 19.

Neon (10 Ne) possesses three stable isotopes: 20Ne, 21Ne, and 22Ne. In addition, 17 radioactive isotopes have been discovered, ranging from 15Ne to 34Ne, all short-lived. The longest-lived is 24Ne with a half-life of 3.38 (2) min. All others are under a minute, most under a second.

Detailed decay information for the isotope neon-19 including decay chains and daughter products.

Nebraska Highway 19 is a highway in Nebraska. It has a southern terminus at the Colorado border south of Sidney and a northern terminus west of Sidney at an intersection with U.S. Highway 30.

In total, 41 transitions from 21 energy levels were measured in Ne-19, with 21 of those transitions being previously unobserved.

Here we report the properties of levels in 19Ne in the excitation energy range of 6.9 ⩽ Ex ⩽ 8.4 MeV studied via the proton-transfer 18F (d,n)Ne* reaction at the Holifield Radioactive Ion Beam Facility. The populated 19Ne levels decay by breakup into p+18F and α+15O particles.

2020年10月6日 · In total, 41 transitions from 21 energy levels were measured in 19Ne Ne 19, with 21 of those transitions being previously unobserved. Of particular importance, transitions from two 3/2+ 3 / 2 + states with energies of 6423 (3) and 6441 (3) keV, crucial for accurate estimations of the 18F(p,α)15O F 18 (p, α) O 15 reaction rate, were found.

Background: Ne19 is an important isotope in nuclear astrophysics due to its role in both the F18 (p,α)O15 and O15 (α,γ)Ne19 reactions in novae and Type I x-ray bursts, respectively. The energy levels of Ne19 near the α and proton thresholds (Sα=3529 keV, Sp=6410 keV) correspond to resonances in both of these reactions.
