Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

We study nature of the low-lying resonance states in mirror nuclei 9Be and 9B. Investigations are performed within a three-cluster model. The model make uses of the hyperspherical harmonics, which provide convenient description of three-cluster continuum. Much attention is paid to the controversial 1/2+ resonance states in both nuclei. We study effects of Coulomb interaction on energy and width of three-cluster resonances in the mirror nuclei 9Be and 9B. We look for the Hoyle-analogue states which allows for alternative way of 9Be and 9B synthesis in a triple collision of clusters.
