vibeqc.default_alpha_for_element

vibeqc.default_alpha_for_element(Z)

Mura-Knowles radial scale α (bohr) for element Z.

Returns a tabulated value for H–Ne; for heavier elements interpolates linearly in Z between the Ne value and a capped value at Z = 30 (≈ 6 bohr) to keep the radial mesh well-resolved without spending nodes far outside the chemically relevant range.

For production-quality work users should override per-element via the alpha parameter on AtomicRadialGrid.from_element().

Parameters:

Z (int)

Return type:

float
