Closed access Metadata (CSL-JSON)

DOI 10.1063/5.0193199

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

Experiment with 48 Ca beam on 238 U target to produce 283 Cn superheavy nucleus was performed at the new gasfilled separator DGFRS-2 on-line to the new cyclotron DC-280 at the SHE Factory at JINR.The maximum beam intensity of 48 Ca was 6.5 pµA and a total beam dose of 2.6×10 19 was collected.Target stability was measured at high intensities of heavy ion beams.16 decay chains of 283 Cn were observed in the 238 U+ 48 Ca reaction.The decay properties of 283 Cn, as well as its α-decay products, were refined.The cross section for the 238 U( 48 Ca,3n) 283 Cn reaction was measured.
