| contents | High accuracy calculations of atomic properties require using long basis sets. In particular, it is necessary to include large number of partial waves and estimate truncation corrections. The convergence in partial waves is known to be rather slow, so calculations become very costly. We use valence perturbation theory [PRA \textbf{105}, 052805 (2022)] to calculate contribution of the high partial waves and estimate truncation corrections. These estimates may be useful to make assessment of theoretical error in atomic calculations more reliable. |
