用质子在中能液氢靶上的非弹性散射研究了~（17），~（19）C核。在多普勒校正的γ谱中观察到两个峰，能量分别为210（6）、331（6）keV（17 C）和72（4）、197（6）keV（19 C），对应于两个核中两个激发态的衰变。通过分析反应截面，确定了这些态的自旋值。实验结果与壳模型计算的结果吻合较好。
17,19C nuclei have been investigated by proton inelastic scattering on a liquid hydrogen target at intermediate energies. Two peaks were observed in the Doppler-corrected γ-ray spectra with energies of 210(6), 331(6) keV in17C and 72(4), 197(6) keV in19C corresponding to the decay of two excited states in both nuclei. Analyzing the reaction cross sections, tentative spin values were determined for the states. The experimental results are in reasonable agreement with the predictions by shell model calculations.
