Description
The two mirror rp-reactions $^{34}$S(p,$\gamma$)$^{35}$Cl and
$^{34g,m}$Cl(p,$\gamma$)$^{35}$Ar were studied via a shell-model approach.
At energies in the resonance region
near the proton-emission threshold many negative-parity states appear.
We present results of calculations in a full (0$+$1)$ \hbar \omega $
model space which addresses this problem. Energies, spectroscopic
factors and proton-decay widths are calculated for input into the
reaction rates. Comparisons are also made with a recent experimental
determination of the reaction rate for the first reaction. The
thermonuclear $^{34g,m}$Cl(p,$\gamma$)$^{35}$Ar reaction rates
are unknown because of a lack of experimental data. The rates for
transitions from the ground state of $^{34}$Cl as well as from the
isomeric first excited state of $^{34}$Cl are explicitly calculated taking
into account the relative populations of the two states. These reaction rates
were then used in post processing studies using NucNet Tools to
understand the impact on classical nova nucleosynthesis.
