  EXO 0748-676 is a well-studied neutron star (NS) Low Mass X-ray Binary (LMXB)
that recently emerged from 16 years of quiescence into a new outburst. Here, we
report the results from a 53 ks XMM-Newton observation to compare with studies
for the previous outburst, particularly focusing on high-resolution
spectroscopy using the same instrument (RGS) that produced important results
for this source during the previous outburst. The EPIC light curve reveals a
type I X-ray burst at MJD 60492.31. The entire data are divided into burstless,
pre-, and post-burst spectra to understand the effect of the burst on the
ionization structure. The spectra for dip and non-dip phases are also created.
The primary spectral feature in all phases is a broad O VII recombination line,
along with velocity-broadened OVIII, NVII, and Ne IX lines. Notably, the Ne IX
line is detected at different ionization states for the pre-burst (11.65 \AA)
and post-burst (13.56 \AA) phases. The O VIII line profile also shows a
difference in equivalent width between dip and non-dip phases. These findings
suggest the presence of highly ionized circumstellar material or collisionally
ionized gas affected by the burst and dips. The source remains in a soft
spectral state, which is consistent with observations during the previous
outburst.
