Abstract

Nuclear mass measurement by electron cooling mode in CSRe is discussed， mainly in three related aspects: the systematic error caused by the space charge effect in the case of linear mass calibration; the possibility of mass measurement of 190 Ir in CSRe; the estimation of the attainable precision in the case of nonlinear mass calibration. Theoretic analysis of the attainable precision shows that a precision of σ(m)/m≈10-8 can be achieved if the momentum spread of each kind of ions can be reduced to 10-6 in CSRe.
