Abstract

Classical novae are potential sources of gamma rays, like the 1.275 MeV gamma emission following Na-22 beta decay, that could be detected by appropriate instruments on board of future satellites like INTEGRAL. It has been shown that the production of Na-22 by novae is affected by the uncertainty onthe Na-21(p, gamma)Mg-22 rate and in particular by the unknown partial widths of the E-x = 5.714, J(pi) = 2(+), Mg-22 level. To reduce these uncertainties, we performed shell model calculations with the OXBASH code, comparedthe results with available spectroscopic data, and calculated the missing partial widths. Finally, we discuss the influence of these results on the Na-21(p,gamma)Mg-22 reaction rate and Na-22 synthesis.
