We present measurements of the bottom-quark production cross sections in pp¯ collisions at √s =1.8 TeV. From the inclusive electron production rate, we... AFE Al - 《Physical Review Letters》 被引量: 380发表: 1993年 Measurement of the W-pair cross-section and of the W mass in $e^...
Cross sections for electron-NH/sup ts+/ recombination have been measured for an electron energy range of 0.065 < or = E < or = 2.00 eV using a trapped-ion ... RD Dubois,JB Jeffries,GH Dunn - 《Phys.rev.a》 被引量: 60发表: 1978年 Photon pair production in expanding hot hadronic ...
The molecule in its ground state is unstable and dissociates. The third component is due to the excited states formed as a result of electron recombination with positive ions along the particle track. The existing data indicate that after the recombination, the VUV photon emission occurs via the...
Transition frequencies were determined with a lowest uncertainty of 3.3 × 10 fractionally. As an application, we determine the proton–electron mass ratio by matching a precise ab initio calculation with the measured vibrational frequency.doi:10.1038/s41567-020-01150-7Ivan Kortunov...
For the first time absolute photon mass energy-absorption coefficients of air in the energy range 3 keV to 10 keV have been measured with relative standard... L Büermann,B Grosswendt,HM Kramer,... - 《Physics in Medicine & Biology》 被引量: 54发表: 2006年 Method of and an apparatus ...
What is the ratio of the energies of a 20GeV electron and a 3keV electron? The metric system: In the metric system, Giga and Kilo are unit prefix in the metric system, which are denoted as; 1G=1091k=103 Electron volt It ...
using an AOM. This work may pave the way for realization of next-generation ultra-compact DAS systems by integration of on-chip opto-electronic devices and modules with the capability of mass-production. Similar content being viewed by others...
Plasma induced ablation mechanism: When an ultrashort duration pulse laser is applied, on one hand, the high peak power of pulse laser can cause multiphoton ionization in tissue whereby the thermalization is mainly depended on recombination processes and electron-phonon inelastic collisions within 10...
