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

Abstract The ground-state static observables and elastic longitudinal (charge) form factors of the 9 Be nucleus in the ground and excited states are considered. The calculations were performed in the framework of the dynamic three-particle 2 α + n -model of the 9 Be nucleus with the Pauli projection. The ground state of the 9 Be nucleus has been calculated in two models distinguished by the α – α interaction—model 1 (Ali-Bodmer potential) and model 2 (Buck–Friedrich–Wheatley potential). For the excited states of 9 Be, wave functions with Ali-Bodmer potential for the α – α interaction are utilized.
