  Ab initio calculations have achieved remarkable success in nuclear structure
studies. Numerous works highlight the pivotal role of three-body forces in
nuclear ab initio calculations. Concurrently, efforts have been made to
replicate these calculations using only realistic nucleon-nucleon (NN)
interactions. A novel local chiral next-to-next-to-next-to-leading order (N3LO)
NN interaction, distinct due to its weaker tensor force, has recently been
established. This paper applies this local NN interaction in ab initio
frameworks to calculate the low-lying spectra of p-shell light nuclei,
particularly 10B, ground-state energies and shell evolution in oxygen isotopes.
Results are compared with calculations utilizing nonlocal chiral N3LO NN and
chiral NN +3N interactions. The ab initio calculations with the local N N
potential accurately describe the spectra of p-shell nuclei, notably the 10B.
Additionally, the neutron drip line for oxygen isotopes, with 24O as the drip
line nucleus, is accurately reproduced in ab initio calculations with the local
NN interaction. Calculations with the local NN interaction also reproduce the
subshell closure at N = 14 and 16, albeit with a stronger shell gap compared to
experimental data. However, the calculated charge radii based on the local NN
interaction are underestimated compared with experimental data, which is
similar to results from the nonlocal NN interaction. Consequently, the present
ab initio calculations further indicate significant spin-orbit splitting
effects with the new local NN potential, suggesting that 3N forces remain an
important consideration.
