Nuclear Data Sheets for A = 140

Population of the2ms+mixed-symmetry state ofBa140with theα-transfe

“…Furthermore, the level energy is consistent with the systematics of 2 + ms states in nearby nuclei [21]. properties indicating mixed-symmetric character is otherwise known in 140 Ba [19].…”

“…This is a factor of 3 lower than the prediction by Alonso et [19]), its missing decay branch to the ground state and its excitation energy not fitting the systematics of MSSs in nearby nuclei.…”

“…This assignment is based on its small E2/M1 multipole mixing ratio δ = 0.18 +0.05 −0.06 determined in β-decay measurements [19]. Furthermore, the level energy is consistent with the systematics of 2 + ms states in nearby nuclei [21].…”

Investigation of thei13/2neutron orbital in theSn132region: New excited levels inKorgul1, Bączyk2, Urban3 et al. 2015Phys. Rev. C

“…The data are taken from Refs. [2,[16][17][18][19][20][21][22][23][24][25][26][27][28]. See text for more details.…”

TAGS measurements of 100Nb ground and isomeric states and 140Cs for neutrino physics with the new DTAS detector

“…2. The detector response to the decay was calculated following the Valencia method [13], i.e., with information of the decay scheme at low excitation energies [23], and the nuclear statistical model at high excitation energies. The expectation maximization (EM) algorithm was applied to extract the I β distribution [12].…”
