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

The thick target inverse kinematics (TTIK) approach was used to measure excitation functions for the elastic $${}^{17}$$ O ( $$\alpha,\alpha$$ ) scattering at the initial $${}^{17}$$ O beam energy of 54.4 MeV. We observed strong peaks corresponding to highly excited $$\alpha$$ -cluster states in the $${}^{21}$$ Ne excitation energy region of 8–16 MeV, which have never been investigated before. Additional tests were done at a $${}^{17}$$ O beam energy of 56.4 MeV to estimate a possible contribution of resonance inelastic scattering.
