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

Neutron-removal cross-section ( σ -xn ) measurements of neutron-rich light nuclei were performed on the COMBAS fragment-separator with a multi-detector Si telescope at intermediate energies (22-34) MeV/nucleon. The removals of one neutron from 8 Li and 9 Be, two neutrons from 6 He and 10 Be and four neutrons from 8 He were observed from the reactions on a Si-CsI(Tl) telescope. Results of σ -xn for 6 He, 8 He, 8 Li, 9 Be and 10 Be nuclei were obtained and compared with those of previously measured data. The data indicate that 4 He is a good core within 6 He and 8 He. Furthermore, we found that 9,10 Be nuclei disintegrated by one- and two- neutron removal reaction, respectively.
