the first image of an electron’s path in the year 2011. Could it be that there are 2 pairs of electrons in HOMO and only one pair in LUMO? A dark band occurs in the middle when \(\lambda\) is low or when \(a_e\) is high (Post "Magic If You Believe"). The center horizontal dark band in picture (a or c) suggests that there is a wide separation between the pair of electrons. A pair atop, left and right close together, and another pair below equally close together, left and right. Between the pairs, wider part than their pair partner. Picture (b or d) has only one pair of electrons.
Definitely interference patterns.
