Lifetime measurements of excited states in ¹⁵O

NUCLEAR REACTIONS ¹⁴N(p, γ)¹⁵O, E=1020, 1570 keV; measured Eγ, Iγ, half-lives of 5.18-, 6.17- and 6.79-MeV levels in ¹⁵O by Doppler-shift attenuation method (DSAM) using three separate, nitrogen-implanted targets with Mo, Ta, and W backings at the Nuclear Science Laboratory (NSL) of University of Notre Dame. Comparison with previous half-life measurements. Monte Carlo simulations of Doppler-shift attenuation factors. R-matrix analysis of asymptotic normalization constants (ANCs) and radiative widths Γ_γ using AZURE2 code for g.s. and levels between 6793 and 9609 keV, including half-lives measured in the present work and experimental data in literature. Relevance to CNO chain of reactions and uncertainty in the ¹⁴N(p, γ)¹⁵O reaction rate.
