The spin-exchange collision cross-section for hydrogen atoms has been measured for the first time in the low temperature range 40100 K by using the polarized hydrogen gas target of the HERMES experiment at DESY (Hamburg, Germany). The results agree with a previous measurement in the overlapping temperature region 80100 K, while seem to hint an increasing behaviour with temperature in the region 5080 K.

Abstract
The spin-exchange collision cross-section for hydrogen atoms has been measured for the first time in the low temperature range 40100 K by using the polarized hydrogen gas target of the HERMES experiment at DESY (Hamburg, Germany). The results agree with a previous measurement in the overlapping temperature region 80100 K, while seem to hint an increasing behaviour with temperature in the region 5080 K.File in questo prodotto:
