Accurate high lying resonance energies of the (3d94s 3D3,2,1)np and the (3d94s 1D2)np (n = 5–40) Rydberg series originating from the (3d104s 1S1/) ground state of the Cu-like Zn+ ion are reported. Calculations are performed in the framework of the Screening Constant by Unit Nuclear Charge (SCUNC) formalism. The results obtained compared very well with high resolution ALS measurements along with DARC, Dirac Atomic R-matrix Codes computations [Hinojoha et al., MNRAS, 470, 4048 (2017)]. Analysis of the present results is achieved in the framework of the standard quantum-defect theory and of the SCUNC-procedure based on the calculation of the effective charge. It is demonstrated that the SCUNC-method can be used to assist fruitfully experiments for identifying narrow resonance energies due to overlapping peaks New high lying accurate resonance energies (n = 16–40) are tabulated as benchmarked data for interpreting spectra from this trans-Fe element in astrophysical objects. •Accurate high lying resonance energies of the (3d94s 3D3,2,1)np and the (3d94s 1D2)np Rydberg series of Cu-like Zn+ reported.•Very good agreement with theory and experiments.•Possibilities to assist fruitfully experiments for identifying narrow resonance energies demonstrated.•New high lying resonance energies tabulated.•Benchmarked data for interpreting spectra of Zn+ ion in astrophysical objects.
