Erratum: Radiative lifetime and energy of the low-energy isomeric level in ${}^{229}\mathrm{Th}$ [Phys. Rev. C 92, 054324 (2015)]

Figure 2

The range of possible radiative linewidths ${\mathrm{\Gamma }}_{\mathrm{rad}}$ (upper scale) and half-lives $T_{1/2}$ (lower scale) of the isomeric state $3/2^{+}3/2\left[631\right](7.8\pm 0.5\mathrm{eV})$ in the ${}^{229}\mathrm{Th}$ nucleus. Calculations are based on values for $B_{\mathrm{W}.\mathrm{u}.}(M1;3/2^{+}3/2\left[631\right]\to 5/2^{+}5/2\left[633\right])$ from Table I (calculated from 1; Ref. [1]: 2; Ref. [2]: 3; Ref. [3]: and 4; Ref. [4]) and, for completeness, Table II (5; Ref. [5]: and 6; Ref. [3]). The refractive index $n\approx 1.5$ increases the probability of the $M1$ transition by a factor of $n^3$ (third row). The Coriolis interaction can lead to a slight increase in the linewidth by a factor of 1.2–1.3 [6] (fourth row). Note the correction to the range in case number 6.

Figure 3

The ranges of possible conversion widths (the upper scale) and lifetimes (the lower scale) of the isomeric nuclear state in a neutral isolated Th atom. The designations are identical with the designations in Fig. 2. Note the correction to the range in case number 6 and the corrected axis for $T_{1/2}^{is}$.
