Abstract

Abstract: A preliminary all-order calculation of the spin-dependent (PNC) amplitude in Cs is carried out in an attempt to understand discrepancies in weak nucleon-nucleon coupling constants derived from atomic and nuclear experiments [W.C. Haxton and C.E. Wieman, Ann. Rev. Nucl. Part. Sci. 51, 261 (2001)]. We find that individual PNC matrix elements significantly change with more complete inclusion of the correlation corrections, whereas changes in the total spin-dependent PNC amplitude are relatively small. Our preliminary value of the anapole coupling constant is only 5% lower than the value used by Haxton and Wieman. [Copyright &y& Elsevier]
