英文摘要	The values of the nuclear electric quadrupole moment are different by about 7% for the Sr-87 nucleus between the recommended value [Stone, At. Data Nucl. Data Tables 111-112, 1 (2016); Pyykko, Mol. Phys. 116, 1328 (2018)] and earlier results [e.g., Martensson-Pendrill, J. Phys. B 35, 917 (2002); Yu, Wu, Gou, and Shi, Phys. Rev. A 70, 012506 (2004)]. In this paper, we report the value Q(Sr-87) = 328(4) mb, making use of our calculated electric-field gradients produced by electrons at the nucleus in combination with experimental values for hyperfine structures of the 5s5p(3)P(1,2) states of the neutral Sr atom. In the framework of the multiconfiguration Dirac-Hartree-Fock theory, the electron correlations were taken into account systematically so as to control the uncertainties of the electric-field gradient at about 1% level. The present result is different from the recommended value, but in excellent agreement with those by Matensson-Pendrill and Yu et al.. We would recommend the present Q value as a reference for Sr-87.
