Energy loss and straggling of He-4 ions in Havar

The energy loss and energy straggling of He-4 ions in Havar foil were measured with the transmission geometry. The present result of energy loss has good agreements with that of the previous experiment and the semi-empirical predictions, while for the energy straggling data significant deviation tvas found at lower energies compared with the predictions of Bohr theory.Physics, MultidisciplinarySCI(E)中国科学引文数据库(CSCD)0ARTICLE7520-5221
