New region of maximum octupole collectivity in the rare-earth nuclei: The case of Gd isotopes
S. Pascu, E. Yuksel, Abhishek, P. Stevenson et autres
We present the first evidence of maximum octupole collectivity in the Gd isotopic chain through a direct measurement of an enhanced B(E3) value in 150Gd. This result was achieved via two highly sensitive experiments designed to determine the lifetime of the first …
