“…Its proton spectroscopic factor has been measured by Garrett, Middleton, & Fortune (1971) to be B0.1. This value is not consistent with the Neogy et al (1972) data and would result, for the 5.714 MeV 22Mg level, in a proton width in excess of the measured 16.5 meV total width. Hence, one may question the isospin triplet assignment made by Endt (1990Endt ( , 1998.…”

“…In addition, the E x \ 6.120 corresponding angular distribution (Fig. 5 of Neogy et al 1972) is very Ñat, presenting no evidence for a direct component and hence a very small neutron spectroscopic factor. This conclusion can be extended to the proton spectroscopic factor in the 22Na mirror level.…”

“…Indeed, the direct comparison of peak E x \ 6.120 heights in the experimental spectrum ( Fig. 1 of Neogy et al 1972) shows that, within levels of the same spin and transferred angular momentum, the cross section for the production of the MeV level is very small.

Neutron spectroscopic factors were obtained by Neogy, Middleton, & Scholtz (1972) for many 22Ne levels, from to 9.07 MeV, but not for the E x \ 0 MeV level because of its very low population and Ñat angular distribution.

Classical novae eject signiÐcant amounts of nuclear-processed material into the interstellar medium. Among the isotopes synthesized during such explosions, two radioactive nuclei deserve particular attention : 22Na and 26Al. In this paper, we investigate the nuclear paths leading to 22Na and 26Al production during nova outbursts by means of an implicit hydrodynamic code that follows the course of the thermonuclear runaway from the onset of accretion up to the ejection stage. New evolutionary sequences of ONe novae have been computed, using updated nuclear reaction rates relevant to 22Na and 26Al production. Special attention is focused on the role played by nuclear uncertainties within the NeNa and MgAl cycles in the synthesis of such radioactive species. From a series of hydrodynamic models, which assume upper, recommended, or lower estimates of the reaction rates, we derive limits on the production of both 22Na and 26Al. We outline a list of nuclear reactions that deserve new experimental investigations in order to reduce the wide dispersion introduced by nuclear uncertainties in the 22Na and 26Al yields.

Proton-induced reaction rates on 26 stable and 29 unstable target nuclei in the mass A \ 20È40 region have been evaluated and compiled. Recommended reaction rates, assuming that all interacting nuclei are in the ground state, are presented in tabular form on a temperature grid in the range T \ 0.01È10.0 GK. Most reaction rates involving stable targets were normalized to a set of measured standard resonance strengths in the sd shell. For the majority of reaction rates, experimental information from transfer reaction studies has been used consistently. Our results are compared with recent statistical model (HauserFeshbach) calculations. Reaction rate uncertainties are presented and amount to several orders of magnitude for many of the reactions. Several of these reaction rates and/or their corresponding uncertainties deviate from results of previous compilations. In most cases, the deviations are explained by the fact that new experimental information became available recently. Examples are given for calculating reaction rates and reverse reaction rates for thermally excited nuclei from the present results. The survey of literature for this review was concluded in 2000 August.
