The $B (E 2)$ anomaly: Evidence for a low-lying mixed-symmetry collective excitation mode

Bo Cederwall, Chong Qi

Exceptionally low values of the ratio of electric quadrupole transition rates, $B_{4/2} \equiv B (E 2; 4_{1}^{+} \to 2_{1}^{+}) / B (E 2; 2_{1}^{+} \to 0_{gs}^{+}) < 1$ , have been obse…

Probing exotic cross-shell interactions at N=28 with single-neutron transfer on 47K

C. J. Paxman, A. Matta, W. N. Catford +76

We present the first measurement of the $^{47}$ K( $d, p I^^{3}$ ) $^{48}$ K transfer reaction, performed in inverse kinematics using a reaccelerated beam of $^{47}$ K. The level scheme of $^{…

Shape evolution in even-mass $^{98 - 104}$ Zr isotopes via lifetime measurements using the $I^^{3} I^^{3}$ -coincidence technique

G. Pasqualato, S. Ansari, J. S. Heines +82

The Zirconium (Z = 40) isotopic chain has attracted interest for more than four decades. The abrupt lowering of the energy of the first $2^{+}$ state and the increase in the transiti…
