Positronium formation in fused quartz: Experimental evidence of delayed formation

The young-age broadening was found and explained with the delayed thermalization of Ps by Stuttgart group. According to the spur or blob model, Ps formation even at ∼100 ps might be possible in suitable materials, such as in fused quartz, even at the room temperature. We have obtained the experiment...

Description
Summary:The young-age broadening was found and explained with the delayed thermalization of Ps by Stuttgart group. According to the spur or blob model, Ps formation even at ∼100 ps might be possible in suitable materials, such as in fused quartz, even at the room temperature. We have obtained the experimental evidence of delayed Ps formation that gives the young-age broadening in fused quartz by the inhibition of slower Ps formation by applying electric fields on it.
