XEUV

(soft X-ray, extreme ultraviolet and ultraviolet)
(electromagnetic radiation in the range of 0.15-400 nm)

The term XEUV (soft X-ray, extreme ultraviolet and ultraviolet) is used for a range covering some astronomical phenomena and attendant studies. Generally the term is meant to cover the less energetic part of the X-ray band (soft X-rays) and all the ultraviolet band including extreme ultraviolet. The cited lower wavelength boundary varies, in the range of 0.1-0.2 nm.
