We have presented atomic data including energies, transition wavelengths, radiative rates and oscillator strengths, which are evaluated for W LXIV, for the lowest 100 fine structure levels and multipole transitions (E1, E2, M1 and also for M2). For W LXIV, we identified the 21 in electric dipole, 33 in electric quadrupole, 28 in magnetic dipole and 21 in magnetic quadrupole soft x-ray (SXR) transitions, as well as 1 in electric dipole extreme ultraviolet (EUV) transitions from the ground state. Furthermore, we have analysed the photoionization cross section and ionization potential of 3s, 3p and 3d levels of Na-like W at five different photoelectron energies by employing the FAC code. Line intensity ratios and electron density for W LXIV have also been reported, which will be useful and necessary for plasma diagnostics, including modelling for future International Thermonuclear Experimental Reactor (ITER) investigations. We assume that our observations will be useful for cell biology, biophysics, fusion plasma research, as well as astrophysical studies and their applications.
