ess.snspowder.powgen.peaks.theoretical_vanadium_dspacing(*, hkl_range=10, min_d=None)[source]#

Return the d-spacing values for vanadium in an ideal case.

Based on the bcc structure of vanadium, the values are

\[d = \frac{a}{\sqrt{h^2 + k^2 + l^2}}\]

where \(a = 3.0272\) Å is the lattice constant of vanadium [Arb18] and \(h+k+l\) is even.

Parameters:

  • hkl_range (int, default: 10) – h, k, l are each limited to the integer interval [0, hkl_range].

  • min_d (Optional[Variable], default: None) – If given, only return values greater than this.

Returns:

Variable – Array of vanadium d-spacing values. Has dimension 'dspacing'.
