✦ Synopsis

Abstract

A treatment of the Bethe‐Salpeter equation leads to additional short‐range interaction terms in the effective‐mass equation of the exciton theory. These non‐Hermitean splitting terms decrease the excitation energies and cause the triplet energy to be the first to become zero if the energy gap is reduced.
