Polish term or phrase: Przejście skośne odwrócone
Szukam anglojęzycznego odpowiednika dla "przejścia skośnie odwróconego" - termin pochodzi z tekstu dot Metod otrzymywania nanokompozytów. Fragment: "Obserwuje się zmianę nachylenia zależności Rdiff (() w zakresie silnej absorpcji światła. Dla SnO2 występują przejścia proste dozwolone w przeciwieństwie do TiO2, dla którego występują przejścia skośne odwrócone." W razie potrzeby zaraz podam dalszą część...

English translation:inverted/reverse indirect transition
Explanation:
indirect transition is rather certain

odwrócone may depend on exact meaning. I will have to study tin oxide.

Previous optical measurements performed 40 years ago showed a strong absorption at 3.75 eV (attributed to direct transitions) and a weaker absorption at 2.62 eV (attributed to indirect transitions).

Transparent Conducting Oxides (TCOs)

However, the band gap is ubiquitously referred to in the literature as 3.75 eV or thereabouts. As shown in previous work (see Ref.: Appl. Phys. Lett. 92 092117 (2008)), the valence band maximum (VBM) in photoemission has been found to lie less than 3 eV below the Fermi energy. An indirect band gap could explain these results,
