A revised program for generating the spin-angular coefficients inrelativistic atomic structure calculations is presented. When compared with ourprevious version [G.Gaigalas, S.Fritzsche and I.P.Grant, CPC 139 (2001) 263],the new version of the Anco program now provides these coefficients for both,scalar as well as non-scalar one-particle operators as they arise frequently inthe study of transition probabilities, photoionization and electron captureprocesses, the alignment transfer through excited atomic states, collisionstrengths, and in many other investigations. The program is based on a recently developed formalism [G.Gaigalas,Z.Rudzikas, and C.F.Fischer, J. Phys. B 30 (1997) 3747], which combinestechniques from second quantization in coupled tensorial form, the theory ofquasispin, and the use of reduced coefficients of fractional parentage, inorder to derive the spin-angular coefficients for complex atomic shellstructures more efficiently. By making this approach now available also fornon-scalar interactions, therefore, studies on a whole field of new propertiesand processes are likely to become possible even for atoms and ions with acomplex structure.
