摘　　要：利用Cowan程序首次计算得到Ar原子价壳层跃迁3p→4p中电单极跃迁和电四极跃迁的广义振子强度,并将理论计算结果与实验结果以及其他理论计算结果进行了比较.结果表明,2个电单极跃迁的广义振子强度计算结果在绝对值上与实验结果符合得较好,只是在峰形上有较明显的差别;3个电四极跃迁的广义振子强度计算结果在强度和峰形上都与实验结果符合得较好,只是第二个极值位置存在微小差别;电单极跃迁总的广义振子强度和电四极跃迁总的广义振子强度的计算结果与实验结果在强度上符合得较好,但在峰形上存在差别.The generalized oscillator strengths（GOS s）for electric monopole and electric quadrupole excitation in 3p→4p of the atoms Ar are calculated using the Cowan program for the first time.Furthermore,they are compared with the experimental results and another theoretical calculation.Seeing from the results,although the calculated GOS s for two monopole excitations are in agreement with the experimental ones in absolute values,there are obvious differences about GOS s profiles.Besides,the calculated GOS＇s for two monopole excitations are in agreement with the experimental ones in absolute values, there are obvious differences about GOS＇s profiles. Besides, the calculated GOS＇s for three quadrupole excitations are in good agreement with the experimental ones, in absolute values and profiles. However, the position of the second maxima of calculated results is different from the experimental ones. The calculated results of the total GOS for electric monopole excitations and the total GOS for electric quadrupole excitations are in agreement with the experimental ones in absolute values, but have differences between them in profiles.
