Abstract: Using the NUSHELLX spherical shell model program, we considered the level structure of ⁹⁴Tc under two different configuration spaces. The calculation results show that the excitation mechanism of positiveparity spin states of ⁹⁴Tc is dominated by the excitation of protons from the p_1/2 orbit into the jg_9/2 orbit across the Z=40
 subshell closure and protons from the (f_5/2,p_3/2) into the (p_1/2,g_9/2) orbit across the Z=38 subshell closure. The negativeparity spin states are the excitation of neutrons from the d_5/2 orbit into the (g_7/2,h_11/2) orbits across the N=56 subshell closure.
