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

Transmission electron-diffraction studies are carried out on N2 O films grown at temperatures 11–18 K and heated slowly to 45 K. The available structural data make it possible to identify the abrupt change in the intramolecular reflection bands observed earlier for N2O films (A. S. Drobyshev et al., Fiz. Nizk. Temp. 20, 600 (1994) [Low Temp. Phys. 20, 475 (1994)]) as a crystallization transformation in which the amorphous component (whose existence at low temperatures is an anomaly exhibited only by N2O cryocrystals; N. V. Krainyukova and M. A. Strzhemechny, Fiz. Nizk. Temp. 21, 1254 (1995) [Low Temp. Phys. 22, 960 (1995)]) loses its metastability near 39–42 K and is transformed into the Pa3 structure as a result of rapid crystallization.
