| Abstract: | Based on experimental data, the photo-induced structural change is interpreted as condensation of triple exciton polarons. The excitonic envelop functions for sin-glet and triplet state are calculated numerically. A possible mechanism of photo-induced structural change is presented and dicussed in detail. |
