摘要
用放化法测量了47MeV/u ^(12)C同^(133)Cs相互作用时碘同位素的产额。发现碘同位素产额分布曲线的峰位在^(124)Ⅰ附近,半宽度为6.5质量单位,最可几产物的质量损失为9.2个质量单位。靶核削裂2个质子的产物^(131)Ⅰ的形成截面约0.47—0.87mb,没观察到靶核削裂2个质子,再俘获1个中子的产物^(132)Ⅰ的活性。
The formation cross sections of iodine isotopes from the intereaction of 47 MeV/u ^(12)C with ^(133)Cs have been measured radio-chemically. The isotopic yield distribution curve has been costructed. It is found that the peak of the curve is in the vicinity of ^(124)I and the curve has a FWHM of 6.5 mass units. The mass loss of the most probable product is 9.2 mass units. The cross section of ^(131)I which is produced by striping of two protons from the target nuclei is 0.47—0.87 mb. The activities of ^(132)I was not observed.
