Abstract

Formation rate of vibrationally excited hydrogen molecules (H₂^*) in a cone-shaped magnetic filter field of an electron cyclotron resonance (ECR) ion source has been investigated by vacuum ultraviolet (VUV) spectroscopy. The spectrum around 121.57 nm peak of Lyman – α was observed up to 162 nm wavelength. The intensity of the band spectrum in the wavelength range has been observed by changing the input microwave power and the gas pressure. Its correlation to the negative hydrogen ion (H^-) production is discussed.
