摘要
在入射电子能量为２５００ｅＶ，散射角为４°—１５°的条件下测量了氦、氖、氩的相对弹性散射微分截面，并采用非弹性散射的广义振子强度为标准进行刻度，得到了２５００ｅＶ能量下的绝对弹性散射微分截面值．
Abstract The relative elastic differential cross sections(EDCSs) of 2500eV electrons scattered by helium,neon and argon atoms were measured at a scattering angle range of 4°—15°.The absolute values of these EDCSs were obtained by normalizing the relative values to the known generalized oscillator strengths.The final results were compared with previous experimental and theoretical results.
