I need to know the spectral emissivity of rhenium for temps roughly from 1000 to 2000 kelvin and can't seem to find the information anywhere. There is an article by Marple from 1956 but I would need to pay 30 dollars for it. Does anyone have access to the article or know another free source of that information?

I think it's 0.36-0.42
