Mass Measurements of Neutron Excessive Nuclei by the (11B,8B) Reactional. (8,9,10), formed in the bombardment of Th by .O. The stability of .Li and of five neutron rich isotopes of Na has been demonstrated by Klapisch et al. (11) using an on-line mass spectrometric technique.

Further, the available accuracy suggests that the effects of electron binding energies, thermal motions of the target nuclei, and target thickness should be re-explored. In fact it is time to ask once again what the measured Q-value determines.作者: 終點(diǎn) 時(shí)間: 2025-3-22 20:24 作者: 兵團(tuán) 時(shí)間: 2025-3-22 22:12

Influence of Atomic Effects on Nuclear Reaction Energiesifetimes of a few nuclear periods. Since such experiments until now were never performed with all the reaction partners beeing bare nuclei and since present day accuracy is in many instances well below 1 keV attention has to be given to the unavoidable interaction of the electronic neighbourhood of the interacting nuclei.作者: 問到了燒瓶 時(shí)間: 2025-3-23 16:50

Studies in Fuzziness and Soft ComputingThe fact that particles do not lose their energy in a target continuously, but in discrete steps, can result in a considerable change of the apparent shape and position of a resonance. A method for determining the shift of the midpoint in a yield curve for thick targets is sketched and numerical results are given in graphical form.作者: 不如屎殼郎 時(shí)間: 2025-3-28 21:34
Representations: From Words to ImagesA set of accurate Q-values has proven to be of some use in many respects.
