Abstract This study presents a simulated quantum computing approach for the investigation into shell-model energy levels of 58 Ni through application variational eigensolver (VQE) method in combination with problem-specific ansatz. The primary objective is to achieve fully accurate low-lying spectrum Ni. chosen isotope, particularly interesting nuclear physics its role astrophysical reactions while also being simple but non-trivial nucleus study, it two particles outside closed shell.

The excited level structures of $^{202}\mathrm{Tl}$ and $^{203}\mathrm{Pb}$, above the ${7}^{+}$ $29/{2}^{\ensuremath{-}}$ isomers, respectively, have been studied. An isomer with ${I}^{\ensuremath{\pi}}={20}^{+}$ ${T}_{1/2}=215(10)\phantom{\rule{4pt}{0ex}}\ensuremath{\mu}\mathrm{s}$ has established in $^{202}\mathrm{Tl}$, scheme extended from $I=10$ to $20\phantom{\rule{0.16em}{0ex}}\ensuremath{\hbar}$ placement fifteen new transitions. In ${I}^{\ensuremath{\pi}}=37/{2}^{+}$ state is be...
In the present work, we have done a systematic shell model study of $N=82$ and $N=126$ isotones. For isotones, performed calculations using SN100PN interaction, while for used KHPE interaction. Similarities between these two isotonic chains been reported, strong resemblance high-$j$ orbitals. Apart from nuclear spectroscopic properties, also explained different isomeric states in regions. $N$ =82 region, mainly discussed properties $6^+$ $17/2^+$ isomers, region $8^+$, $11^-$, $21/2^-$...
We present systematic large-scale shell-model calculations for Rn isotopes with $A=$ 207 to 216. For the $^{207-212}$Rn isotopes, we perform KHH7B interaction, while $^{213-216}$Rn KHPE and interactions. The calculated energies electromagnetic properties are compared available experimental data predicted where not available. also suggest spins parities of several unconfirmed states from recent data. Comprehensive study isomeric configurations half-lives is reported.
In the present work available experimental data up to high-spin states of $^{119-126}$Sn isotopes with different seniority ($v$), including $v$ = 4, 5, 6, and 7 have been interpreted shell model, by performing full-fledged model calculations in 50-82 valence composed $1g_{7/2}$, $2d_{5/2}$, $1h_{11/2}$, $3s_{1/2}$, $2d_{3/2}$ orbitals. The results compared data. These are described terms broken neutron pairs occupying $h_{11/2}$ orbital. Possible configurations isomers these nuclei...
Isomers with three- and five-nucleon-hole configurations have been established in $^{203}\mathrm{Tl}$. These include newly identified levels a three-nucleon-hole structure: ${I}^{\ensuremath{\pi}}$ = ($15/{2}^{\ensuremath{-}}$) ${T}_{1/2}$ 7.9(5) ns ($35/{2}^{\ensuremath{-}}$) 4.0(5) ns. In addition, states also established: ($39/{2}^{\ensuremath{-}}$) 1.9(2) ($49/{2}^{+}$) 3.4(4) The previously determined long-lived decay, 6.6(3) $\ensuremath{\mu}\mathrm{s}$ from this work, is associated...
We have reported shell-model results for $^{47-58}$Ca isotopes in the $fp$, $fpg_{9/2}$ and $fpg_{9/2}d_{5/2}$ model spaces using realistic $NN$ interaction. also performed a systematic study interactions derived from in-medium similarity-renormalization group (IM-SRG) targeted particular nucleus with chiral $3N$ forces. The obtained are reasonable agreement available experimental data $fp$ space It is shown that $g_{9/2}$ $d_{5/2}$ orbitals play an important role heavier neutron-rich...
