Nuclear Data Sheets for A=98

Zr Isotopes as a region of intertwined quantum phase transitions

“…Note that the calculated values start at neutron number 52, while the experimental values include the closed shell at 50. Data taken from [53] ( 92 Zr), [54] ( 94 Zr), [55] ( 96 Zr), [57] ( 98 Zr), [58] ( 100 Zr), [59] ( 102 Zr), [66] ( 104 Zr), [67] ( 106 Zr), [68] ( 108 Zr), [30,69] ( 110 Zr). 4/2 = 3.24 larger, suggesting further increase in deformation.…”

“…Notation as in Fig.4. Data taken from[33,57] for 98 Zr, from[29,58] for 100 Zr and from[59] for 102 Zr.…”

Tests of collectivity in $^{98}$Zr by absolute transition rates

“…Using the measured lifetimes, and the information on the conversion coefficients, the multipolarity mixing ratios and the branching ratios from Ref. [11], the reduced transition probabilities are calculated and the results are presented in Table III. One can attempt to use the branching of the 2 + 2 → 0 + 3 transition, measured in Ref.…”

“…[40] and evaluated in Ref. [11], in order to estimate the reduced transition probability. However, this leads to an unrealistically large B(E2) value and, furthermore, the indicated branching ratio was not confirmed by the more recent measurement in Ref.…”

“…The energies of the first excited 2 + states for Zr and Sr isotopes with N = 52−62 (symbols connected by a solid line), together with the B(E2; 2 + 1 → 0 + 1 ) (symbols connected by a dashed line). Data are taken from the nuclear data sheets [7][8][9][10][11][12][13]. The B(E2; 2 + 1 → 0 + 1 ) value for 98 Zr is taken from [14].…”
