Query: A study of open shell nuclei using chiral two-body interactions   We apply the Hybrid-Multi-Determinant method using the recent chiral two-body
interactions of Entem-Machleidt-Nosyk (EMN) without renormalization to few
nuclei up to A=48. Mostly we use the bare fifth order NN interaction N4LO-450.
For ${}^{24}Mg$ and ${}^{48}Cr$ the excitation energies of the $2^+_1$ states
are far larger than the corresponding experimental values.
