Abstract
Absorption spectrum of a system of two closely spaced identical atoms displays, at certain preparation, a dip that can be much narrower than the natural linewidth. This preparation includes (i) application of a strong magnetic field at an angle $\ensuremath{\alpha}$, that is very close to the magic angle ${\ensuremath{\alpha}}_{0}=arccos(1/\sqrt{3})\ensuremath{\approx}{54.7}^{\ensuremath{\circ}}$, with respect to the direction from one atom to another, and (ii) in-plane illumination by a laser light in the form of a nonresonant standing wave polarized at the same angle $\ensuremath{\alpha}$. Both qualitative and quantitative arguments for the narrow dip effect are presented.
