The atomic number density(N; atoms/cm3) is the number of atoms of a given type per unit volume (V; cm3) of the material. The atomic number density (N; atoms/cm3) of a pure material having anatomic or molecular weight(M; grams/mol) and thematerial density...

The use of a room temperature flow reactor as a reference source allows for absolute calibration of relative number density measurements while removing many constants, and their uncertainties, from the calculation. Temperature and number density measurements in the free stream of air and nitrogen ...

the length of body-ordered descriptors, such as the SOAP power spectrum (3-body) and the (ACE) (multiple body-orders), scales as (NS)ν where ν + 1 is the body-order and N is the number of radial basis functions used in the density expansion. We introduce two distinct ...
