| 摘 要： | 用相对论平均场模型结合NL3、TM2和NL-SH参数对P的奇A核同位素的2s1/2和1d3/2单质子能级变化趋势以及自旋和宇称进行了理论计算.发现丰中子同位素37-47P,尤其是47P中可能存在2s1/2和1d3/2单质子能级反转.对于37P和39P,TM2和NL-SH参数给出的自旋和宇称是（3/2）＋,NL3给出的是（1/2）＋；对于41-47P,NL3、TM2和NL-SH给出的自旋和宇称都是（3/2）＋.自旋和宇称的结果只有部分和NUBASE2012中的估计值是一致的.

| Abstract: | The 2sl/2 and ld3/2 single-proton energy levels and the spin and parity values of the odd-A P isotopes are studied by using the relativistic mean field model with the NL3, TM2 and NL-SH parameters. Results show that the 2Sl/2 and ld3/2 proton level inversion may exist in the neutron-rich isotopes 37-47p, especially in 47p. For the spins and parities, the predictions for 37p and 39p with TM2 and NL-SH parameters are （3/2）＋, and those with NL3 are （1/2）＋; the predictions for 41-47p with TM2, NL-SH and NL3 are all （3/2）＋. Only part of the results of the predicted spin and parity values agree with the estimates given by the NUBASE2012. |
