High-spin states of ¹⁴⁵Sm were studied by using the reactions ²⁰Ne(¹³⁶Xe,α7n), ¹⁶O(¹³⁶Xe,7n), ¹³⁹La(¹⁰B,4n) and ¹³⁸Ba(¹³C,6n). The level scheme was extended up to the state at 14.6 MeV. The excitation energy and the spin-parity of the 0.96 μs high-spin isomer were determined to be 8.8 MeV and (49/2⁺), respectively. Experimental results were discussed comparing with the deformed independent particle model calculation. High-spin isomers observed in N = 83 isotones were interpreted to be caused by the sudden shape change from near spherical to oblate. The Z = 64 shell gap energy was found to decrease from 2.4 to 2.0 MeV as the proton number decreases from Z = 64 to 61.
