Abstract Radioactive119Sb was implanted into six host matrices (CaSnO3, Pt, Y, Au,Β-Sn, Pb) and internal conversion electrons of the 23.87 keV transition in119Sn were measured with an iron-free magnetic spectrometer as well as Mössbauer spectra. In the analysis of the conversion spectra of outermost electrons, the overlapping K-LM Auger lines were subtracted using the Auger spectrum of tin measured with another source of117mSn, and the shake-off effect accompanying the conversion process was considered. From the correlation between the Mössbauer isomer shifts and the intensity ratios of O-shell to N1-shell conversion electrons, the change of the nuclear charge radius of the 23.87 keV transition of119Sn was deduced to be δR/R=(0.87 ± 0.25) × 10−4 for a uniform charge distribution ofR= 1.2 ×A 1/3 fm or, equivalently, δ 〈r2〉—=(3.6 ± 1.0) ×10−3 fm2.
