After few femtoseconds, the double excited state decays by electron emission, generating a higher charge state. Compared to ...

Researchers have for the first time measured the first ionization energy of lawrencium, the last of the actinides, validating predictions of the element’s electronic structure (Nature 2015, DOI: ...

Energy is transferred to the absorber during the ionisation process. For a given thickness of absorber, alpha radiation produces most ionisation, beta next and gamma least. Safety precautions are ...

Proceedings of the Royal Society of London. Series A, Mathematical and Physical Sciences, Vol. 253, No. 1272 (Nov. 17, 1959), pp. 37-51 (17 pages) The ionization produced within diamond specimens by ...

Markes International, a world leader in instrumentation for trace organic analysis, has announced the launch of a variable-energy electron ionisation source technology for GC-MS, Select-eV. By ...
