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

Preliminary results of measurements of the total reaction cross sections σ R and neutron removal cross section σ -xn for weakly bound 6 He, 8 Li, 9 Be and 10 Be nuclei at energy range (20-35) A MeV with 28 Si target is presented. The secondary beams of light nuclei were produced by bombardment of the 22 Ne (35 A MeV) primary beam on Be target and separated by COMBAS fragment-separator. In dispersive focal plane a horizontal slit defined the momentum acceptance as 1% and a wedge degrader of 200 μm Al was installed. The Bρ of the second section of the fragment-separator was adjusted for measurements in energy range (20-35) A MeV. Two-neutron removal cross sections for 6 He and 10 Be and one –neutron removal cross sections 8 Li and 9 Be were measured.
