Helium droplets doped with Xe and Kr atoms were photoionized by using VUV synchrotron radiation from the Advanced Light Source and the resulting photoelectron images were measured. A wide range of He droplet sizes, photon energies, and dopant pick-up conditions was investigated. Significant ionization of dopants was observed at 21.6 eV, the absorption maximum of 2p (1)P1 electronic excited stat...
Coalbed methane (CBM) is an important energy source globally, thus understanding its origin and evolution essential to the assessment of reserves developing exploration strategies. This study aims identify CBM in Liupanshui Coalfield (LPC) southern China evaluate influence basin exhumation on gas storage different rank coals. Ten samples were collected from four blocks that have thermal histori...
Optimizations of gas composition and input energy were performed for gas mixtures containing a buffer gas and either Ar, Kr or Xe as the lasing gas. The total gas pressure was varied between 1 and 14 bar and the input energy from 0.03 to 0.7 J/cm 3. The excitation source was a small coaxial electron beam with a pumping length of 20 cm and a pulse length of 30 ns (FWHM). From an active volume of...
Four-photon excitation of autoionizing states of Ar, Kr, and Xe between the2P3/2and2P1/2ionic limits
