Differential and total cross sections of the γp→π~0 p and the γp→π~0 pn reaction were measured for photon energies between 640 and 1 150 MeV.The data have been compared with SAID and MAID model calculations.π~0 photoproduction on the deuteron shows a strong suppression of the 2nd resonance which is clearly seen in the γp→π~0 p reaction. 相似文献

Fe-Cr-Ni, Ni-Al and Ni-Si alloys, and 316L stainless steels as reference were electron-irradiated using a high voltage electron microscope (1MV), and in-situ observations of structural evolution and micro-chemical analysis were carried out. From the compositional analysis it was found that nickel was enriched and chromium depleted near grain boundary in Fe-Cr-Ni alloys including 316L stainless steels, and that simultaneously grain boundary migration was caused during irradiation, even if no grain boundary migration occurred in the un-irradiated area at the same irradiation temperature. The occurrence of boundary migration strongly depended upon orientation relationship between boundary interfaces. It is suggested that grain boundary migration under irradiation remarkably occurs in the alloys in which solute enrichment is taken place at the grain boundary as a result of the flow of radiation-introduced point defects into grain boundary and that their magnitude depend upon net flow of point defect, especially that of under-sized interstitial atoms. 相似文献

Abstract Efficient methods of desulfation are often required in carbohydrate chemistry and biochemistry. In addition to conventional desulfation methods,1,2 we recently reported a novel desulfation method employing a silylating reagent, N,O-bis(trimethylsilyl)-acetamide.3,4 With this reagent, the 6-O-sulfoxyl groups of the sugar moiety are regioselectively removed and newly formed hydroxyl groups are further converted by silylation into trimethylsilyloxyl groups. The desulfated carbohydrates are easily recovered after desilylation with water or aqueous methanol. Although the mechanism for this reaction remains unclear, silylating reagents can be considered as potential reagents for desulfation reaction. In the present paper, we examined various silylating reagents to find effective and new desulfation reagents for carbohydrate sulfates. 相似文献

In this paper, we show that Bennequin's inequality is highly non exact with respect to Legendrian simple closed curves of
certain topological types.
