Asymptotic normalization of mirror states and the effect of couplings

and the core is allowed to excite. We apply the model to 8 Li/ 8 B, 13 C/ 13 N, 17 O/ 17 F, 23 Ne/ 23 Al, and 27 Mg/ 27 P. Our results show that for most studied cases, the ratio between asymptotic normalization coefficients of mirror states is independent of the strength and multipolarity of the couplings induced. The exception is for cases in which there is an s-wave coupled to the ground state of the core, the proton system is loosely bound, and the states have large admixture with other configurations. We discuss the implications of our results for novae.
