Experimental observation of energy losses of 0.7 MeV protons, which were specularly reflected at a clean (001) surface of SnTe single crystal is reported. Comparison has been made of the observed losses with those calculated from theoretical models, in which the dynamical response of solid electron...
为验证爱因斯坦质能方程△E=△mc2的正确性,设计了如下实验:用动能为E1=0.6 MeV的质子轰击静止的锂核Li,生成两个α粒子,测量两个α粒子的动能之和为E2=19.9 MeV。 (1)写出该核反应方程; (2)通过计算说明△E=△mc2正确。(已知质子、α粒子、锂核的质量分别为mp=1.007 3 u,mα=4. 001 5 u,mLi=7.016 ...

Angular and energy distributions of dissociated fragments resulting from glancing angle incidence of MeV Hions on clean (001) surfaces of SnTe single crystals in UHV are studied. The distributions are compared with those obtained for Hprojectiles of the same velocity. It is shown that the molecula...
