The measurement of the relative isotopic position of an element, necessary for the detection of an instability in the nuclear volume effect, was carried out on strontium isotopes. The isotopic displacements of the isotopes Sr/ sup 84/, Sr/sup 86/, Sr/sup 88/, and Sr/sup 90/ were determined with a photoelectric recording Fabry-Perot spectrometer. The results are tabulated and show that for the 84, 86, and 88 isotopes a displacement in the direction of volume dependent effects is observed. The isotopic displacement between the 88 and 90 isotopes has the sign of the nuclear volume effect. To evaluate the nuclear volume effects trom the isotopic displacements. the volume dependent effect was determined. The values are tabulated. A comparison is also given of the discontinuity of the nuclear volume effect at neutron numbers of 50, 82. and 126 with respect to the ratio beta C/sub ext//C/sub th/ (the ratio of the observed nuclear volume effect to the nuclear volume effect calculated for homogeneous charged spherical nuclei).
