### Abstract

We search for low-lying resonances in the [Formula Presented] and [Formula Presented] nuclei using a microscopic cluster model and a variational scattering method, which is analytically continued to complex energies. After fine-tuning the nucleon-nucleon interaction to get the known [Formula Presented] state of [Formula Presented] at the right energy, we reproduce the known spectra of the studied nuclei. In addition, our model predicts a [Formula Presented] state at 1.3 MeV in [Formula Presented] relative to the [Formula Presented] threshold, whose corresponding pair is situated right at the [Formula Presented] threshold in [Formula Presented] Lacking any experimental evidence for the existence of such states, it is presently uncertain whether these structures really exist or whether they are spurious resonances in our model. We demonstrate that the predicted state in [Formula Presented] if it exists, would have important consequences for the understanding of the astrophysically important [Formula Presented] reaction.
