我们建立了可用于1H ~ 83Bi的无脱垂高斯基集,并提出了随着展开项的增加,dirac - fock - roothan (DFR)总能量(TE)向数值DF (NDF) TE单调减小的条件。假设一个均匀的基集。对于小于或等于83Bi的原子,得到| <或= 1 × 10(-6) hartree;TE(NDF) = -21 565.638 345, TE(DFR) = -21,565.638 345 +/- 0.000 001 hartree,当展开式项分别在(58,58,58,36,36,36,36)和(72,72,72,72,36,36,36,36)范围内(s+, p-, p+, d-, d+, f-, f+)对称时,对于Bi, TE(NDF) = -21 565.638 345 +/- 0.000 001 hartree。在|TE(DFR) - TE(NDF)| <或= 4 × 10(-5)的情况下,还提出了一个具有44、44、44、36、36、32和32的实用集合。
We have developed prolapse free Gaussian basis sets which can be used for 1H to 83Bi, imposing the condition that the Dirac-Fock-Roothaan (DFR) total energy (TE) decreases monotonically toward the numerical DF (NDF) TE as the expansion term increases. An even-tempered basis set was assumed. The resulting sets gave |TE(DFR) - TE(NDF)| < or = 1 x 10(-6) hartree for any atoms less or equal to 83Bi; TE(NDF) = -21 565.638 345, and TE(DFR) = -21,565.638 345 +/- 0.000 001 hartree for Bi when the expansion terms are in the range (58, 58, 58, 36, 36, 36, and 36) and (72, 72, 72, 36, 36, 36, and 36) for (s+, p-, p+, d-, d+, f-, and f+) symmetries, respectively. A practical set with 44, 44, 44, 36, 36, 32, and 32 for the respective symmetries is also proposed where |TE(DFR) - TE(NDF)| < or = 4 x 10(-5).
