step background

step description prompt

Write a Python function to determine the alpha value for the Ewald summation given reciprocal lattice vectors `recvec` of shape (3, 3). Alpha is a parameter that controls the division of the summation into real and reciprocal space components and determines the width of the Gaussian charge distribution. Multiply the result by scaling `alpha_scaling` (fixed to 5).
