Lifetime of the 6793-keV state in 15O.
The energy derived from the CN cycle at low stellar temperatures is regulated by the 14N(p,gamma)15O reaction. A previous direct measurement of this reaction has been interpreted as showing evidence for a subthreshold resonance which makes a major contribution to the reaction rate at low temperatures. This resonance, at E(c.m.) = -504 keV would correspond to the known Ex = 6793-keV state in 15O...
متن کاملLow Energy Measurement of the 18F(p,α)15O Cross Section at TRIUMF
An experiment to measure the 18F(p,α)15O cross section at low centre of mass energies has been performed with the TRIUMF-UK Detector Array (TUDA) facility at TRIUMF. Measurements of the 18F(p,α)15O reaction rate at four separate centre of mass energies; 665 keV, 430 keV, 330 keV and 250 keV, were carried out. The main goal of the experiment was the measurement of the 18F(p,α)15O cross section b...
متن کاملThe 14 N ( p , γ ) 15 O low - energy S - factor
The 14N(p,γ )15O low-energy S-factor is analyzed using the R-matrix model. We find that the g.s. contribution is less than previously reported. The S-factor is mainly given by the 6.79 MeV state contribution which is determined by its asymptotic normalization constant (ANC). Consequently, the S-factor at zero energy is lower by a factor of 1.7 compared to the values given in recent compilations...
متن کاملMeasurement of (α,n) reaction cross sections of erbium isotopes for testing astrophysical rate predictions
The γ-process in core-collapse and/or type Ia supernova explosions is thought to explain the origin of the majority of the so-called p nuclei (the 35 proton-rich isotopes between Se and Hg). Reaction rates for γ-process reaction network studies have to be predicted using Hauser-Feshbach statistical model calculations. Recent investigations have shown problems in the prediction of α-widths at as...
متن کاملExcitation of Giant Resonances in Deuteron Stripping Reactions on 10B far below the Coulomb Barrier
The reaction threshold for deuteron induced reactions on B amounts to 25.2 MeV, which enables an excitation of the giant resonances (GR) in the compound nucleus C even at very low projectile energies. In our recent experimental and theoretical investigations of the B(d,p)B reaction, we have found a strong reaction contribution arising from the giant dipole resonance (GDR) excitation. This kind ...
