论文摘要
碳$ 2^+$状态的激发在4.439 meV（$ 70-150 $ MEV电子冲击）及其随后通过光子发射对基态的衰减，在扭曲的波生诞生的近似中描述了。过渡密度是从核准粒子声子模型获得的。将光子角分布与早期的结果和实验进行了比较，包括Bremsstrahlung的影响。在极化电子撞击的情况下，自旋不对称的预测。
The excitation of the carbon $2^+$ state at 4.439 MeV by $70-150$ MeV electron impact and its subsequent decay to the ground state by photon emission is described within the distorted-wave Born approximation. The transition densities are obtained from the nuclear quasiparticle phonon model. The photon angular distributions are compared with earlier results and with experiment, including the influence of bremsstrahlung. Predictions for spin asymmetries in the case of polarized electron impact are also made.
