The decay of 157Ho to 157Dy ( T 1 2 = 12.6 min) was investigated by means of Ge(Li) and Si(Li) detectors. With the help of a multidimensional coincidence device, we propose a scheme with several levels explained in terms of the single-particle Nilsson model....
PAR聚合物是一种聚芳酯,其分子主链上带有芳香族环和酯键。由于主链芳环密度高,使其热变形温度达到了175℃,具有良好的耐热性。此外,它的主链含有对位和间位苯环链节,这阻碍了聚合物分子结晶,从而形成了无定形透明聚合物,具有良好的透明性。PAR聚合物...
