The generally accepted mechanism for this reaction is the classical addition-elimination sequence that involves the formation of a Meisenheimer- type intermediate 1 (Scheme 33.1).doi:10.1007/978-3-642-18788-9_33Mar Gómez GallegoMiguel A. Sierra...
A-level生物的主要难点在于，你不得不记很多新词汇，长得都差不多，但意思却相差很远。添加文蓝君V：guojijun01获取Alevel/IGCSE词汇手册~A-level生物的mark scheme也比较具有迷惑性，就算你理解具体的概念有时候也很难得分，因为可能要求用特定的术语以特定的方式来展示这个概念或知识。总结一下，一开始学习A-level...
The level scheme of 91 Nb has been investigated with the reaction 90 Zr( p , γ) 91 Nb. Proton energies between 3.0 and 7.2 MeV were used. The γ spectra were taken with Ge(Li) detectors. Primary γ transitions to 36 excited states of 91 Nb up to 3.8 MeV excitation energy and many...
摘要: The 8.998-MeV resonance level excited by the (γ,γ′) reaction, which was previously assigned to 150Sm, is shown to belong to 144Sm. The level scheme of 144Sm is given and the re-evaluated level parameters of the 8.998-MeV resonance are presented....

The reaction used was 24Mg(14N,α p)33S at a beam energy of 40MeV. An analysis of DCO ratios and triple gamma coincidences was performed. So far, a new level depopulated by 3 γ -ray transitions has been found and its spin was determined. The work for further extension of the level...
