This is the repository to provide updated version of the results discussed in the following article:
Uncertainty quantification in the nuclear shell model

DOI: 10.1103/PhysRevC.98.061301
New 0p-shell interaction: z_mass.int
This is the latest 0p-shell interaction for the 0p-shell in isospin-formalism. This is optimized to the "original" 33 data set in the pioneering work by Cohen and Kurath: S. Cohen and D. Kurath, Nucl. Phys. 73, 1 (1965).
The integers 3 and 4 represent the p1/3 and p3/2 orbits respectively.
The interaction in the input format for KSHELL is also available. -> [z_mass.snt]
pshell_data.txt
Experimental and calculated results are summarized in [pshell_data.csv]
Jnum: total angular momentum
JTN: The "specifier" of the states. For example, (JTN=2+0,3) means the third lowest Jpi=2+ and T=0 state.
Eexp: Experimental energy eigenvalues from ENSDF (Note: This can be outdated)
ExExp: Experimental excitation energies of the states
CKE(CKEx): Calculated energy eigenvalues (excitation energies) using the Cohen Kurath interaction (CKtb1 in our paper)
EMAP(ExMAP): Results with the z-mass interection
LA: mean values energy eigenvalues with 50,000 LA (Laplace Approximation) samples.
LAsig: one standard deviaiton of the LA result
Eim4(Exim4): Results with VS-IMSRG 500/400
Eim5(Exim5): Results with VS-IMSRG 500/500
infit: whether or not used in parameter fitting
Remarks on LA families:
"(1)" means that the Hessian matrix is evaluated only with the first derivative terms
"ex" is used to abbreviate "excitation energy"
For VS-IMSRG results (Eim4&Eim5):
