Abstract: Isochronous mass spectrometry has been applied in the storage ring CSRe to measure the masses of the Tz=−3/2 nuclei ²⁷ P and ²⁹ S. The new mass excess value ME(²⁹ S)=−3094(13)keV is 66(52) keV larger than the result of the previous ³² S(³ He, ⁶ He) ²⁹ S reaction measurement in 1973 and a factor of 3.8 more precise. The new result for ²⁹ S together with those of the T=3/2 isobaric analog states in ²⁹ P, ²⁹ Si, and ²⁹ Al fit well into the quadratic form of the isobaric multiplet mass equation (IMME). The mass excess of ²⁷ P has been remeasured to be ME(²⁷ P)=−685(42)keV. By analyzing the linear and quadratic coefficients of the IMME in the T_z =−3/2 sd-shell nuclei, it was found that the ratio of the Coulomb radius parameters is R≈0.96 and is nearly the same for all T=3/2 isospin multiplets. Such a nearly constant R value, apparently valid for the entire light mass region with A>9, can be used to set stringent constraints on the isovector and isotensor components of the isospin nonconserving forces in theoretical calculations.
