摘要
The Excited states of ^(88)Sr have been produced in the reaction ^(16)O(^(82)Se,4p6n)and studied using the in-beam γ spectroscopy techniques.Two high-spin level structures have been observed and established up to 8.5 MeV and 7.9 MeV excitation energy,respectively.Based on the measurements of the directional correlations ofγ-rays de-exciting oriented states and anisotropic factors ofγ-rays,spin values of the excited states have been assigned up to the highest levels observed.
