  Atomic Compton profiles (CPs) are a very important property which provide us
information about the momentum distribution of atomic electrons. Therefore, for
CPs of heavy atoms, relativistic effects are expected to be important,
warranting a relativistic treatment of the problem. In this paper, we present
an efficient approach aimed at ab initio calculations of atomic CPs within a
Dirac-Hartree-Fock (DHF) formalism, employing kinetically-balanced Gaussian
basis functions. The approach is used to compute the CPs of noble gases ranging
from He to Rn, and the results have been compared to the experimental and other
theoretical data, wherever possible. The influence of the quality of the basis
set on the calculated CPs has also been systematically investigated.
