利用安装在ISOCELE设施上的PILIS（后ISOCELE激光等柱分离）设备，对185,187,189,191,195铂进行了同位素位移（IS）和超精细结构（HFS）测量。磁矩和四极矩由HFS的结果推导出来。从IS结果中确定的这些奇核的变化半径变化，加上偶核的δ <r2>值，与不对称解的晶格Hartee-Fock+BCS计算结果进行了比较。185Pt被证实为长形，而187,189,191 pt在基态可能是三轴形。
Isotope shift (IS) and hyperfine structure (HFS) measurements have been performed for185,187,189,191,195Pt using the PILIS (Post ISOCELE Laser Isobar Separation) apparatus installed at the ISOCELE facility. Magnetic and quadrupole moments have been deduced from the HFS results. The change radius changes determined for these odd nuclei from the IS results, added to the δ <r2> values of the even-A nuclei, are compared to the results of lattice Hartee-Fock+BCS calculations for asymmetric solutions.185Pt is confirmed to be prolate shaped whereas187,189,191Pt are likely triaxial in their ground states.
