Numerical details

All calculations presented below were
done by using the code HFODD [26,37], version (2.48q) or higher, which
includes both the angular-momentum and isospin projections.
In order
to obtain converged results for isospin mixing with respect to basis
truncation, in our SV calculations we used harmonic oscillator (HO) shells for nuclei,
12 shells for
nuclei, and 14
shells for nuclei. In SHZ2 test calculations, we took
shells for and shells for nuclei.

For the numerical integration over the Euler angles in space and
isospace (
) we used the
Gauss-Tchebyschev (over and ) and Gauss-Legendre
(over and ) quadratures. We took
and
(or 10) integration points.
This choice guarantees that the calculated values of
are not affected by the numerical integration error.
