A double-slit experiment is analysed when the interfering particle has an internal structure and one endeavours to obtain ‘which path’ information by detecting the light that is spontaneously emitted. A compact expression is derived for the visibility of the interference pattern: coherence depends on both the spatial and temporal features of the emission process during the travel of the particle to the screen. A bound is set on the temperature of a fullerene molecule in a double-slit experiment in order that its quantum mechanical coherence be maintained.

Abstract
A double-slit experiment is analysed when the interfering particle has an internal structure and one endeavours to obtain ‘which path’ information by detecting the light that is spontaneously emitted. A compact expression is derived for the visibility of the interference pattern: coherence depends on both the spatial and temporal features of the emission process during the travel of the particle to the screen. A bound is set on the temperature of a fullerene molecule in a double-slit experiment in order that its quantum mechanical coherence be maintained.File in questo prodotto:
