A Further Measurement of the beta-Delayed alpha-Particle Emission of 16N
R. H. France, E. L. Wilds, J. E. McDonald +1
We measured the beta-delayed alpha-particle emission spectrum of 16N with a sensitivity for beta-decay branching ratios of the order of 10-10. The 16N nuclei were produced using th…
In Beam Tests of Implanted Helium Targets
J. E. McDonald, R. H. France, R. A. Jarvis +22
Targets consisting of 3,4He implanted into thin aluminum foils (approximately 100, 200 or 600 ug/cm^2) were prepared using intense (a few uA) helium beams at low energy (approximat…
Absolute Branching Ratio of Beta-Delayed Gamma-Ray Emission of N18
R. H. France, Z. Zhao, M. Gai
The absolute branching ratio of the beta-delayed gamma-ray emission of N18 was measured, providing absolute normalization of the previous work by Olness et al. [J.W. Olness et al.,…
How Well Do We Know the Beta-Decay of N16 and Oxygen Formation in Helium Burning?
Ralph H France, Moshe Gai
Contrary to claims that the problem has been solved, the astrophysical E1 S-factor of \c12ag is not yet well known. R-Matrix analyses of elastic scattering data,\c12ag data, and da…
How Well Do We Know the Beta-Decay of 16N and Oxygen Formation in Helium Burning
Moshe Gai
We review the status of the 12C(a,g)16O reaction rate, of importance for stellar processes in a progenitor star prior to a super-nova collapse. Several attempts to constrain the p-…
Comment on Constraints on the Low-Energy E1 Cross Section of 12C(alpha,gamma)16O from the Beta-Delayed Alpha Spectrum of 16N
Ralph H. France, Moshe Gai
We dispute the alteration by Azuma et al. of the energy calibration of the Mainz('71) data on the beta-delayed alpha-particle emission of as well as the very justification…
