“…The wellknown 219-635 keV, 0 Table II, were used to confirm the measurement and analysis procedure. The A 2 and A 4 coefficients obtained for these cascades agree (4) 63 (6) 50 (10) (7) 35 (4) 39 (6) (5) 70 (6) 100 (20) (2) 37 (8) (2) 45 (8) (17) 15 (5) 15 (3) (2) 14 (2) (4) 14 (5) a Level spin assignments are nominal assignments from the evaluation [22], except as noted.…”

“…74 Br has two β-decaying states [22], the ground state with spin and parity J π = (0 − ) and T 1/2 = 25.4 min and an isomeric state with spin and parity J π = 4 (+) and T 1/2 = 46 min. The experiment was performed with a beamon/beam-off cycle of 1 hour.…”

“…The levels populated in 74 Se and their γ-decay are summarized in Table I. Branching ratios from excited levels are compared with the current literature [22] values. Levels which were observed in a previous study [19] of the decay of the J π =(0 − ) ground state but not in the decay from the J π =4 (+) isomer [20,21] are indicated by a *.…”

Nuclear mean-square charge radii of63,64,66,68−82Ga nuclei: No anomalous behavior atN=32Procter1, Billowes2, Bissell3 et al. 2012Phys. Rev. C301210View full textAdd to dashboardCite

“…This paper will present the charge radii values of the 63,64,66,68−82 Ga nuclei along with previously unmeasured nuclear gs spin and moment values. + /2 + energy levels in Zn (circles) and Ge (triangles) isotopes [7][8][9][10][11][12][13][14][15][16][17][18]. Noticeable effects are observed at N = 50 and N = 38; however, no clear effects are seen below N = 38.…”
