B(E2

A smooth onset of collectivity in Kr^(88,92,94,96) has been determined from reported B(E2; 2_(1)^(+) → 0_(1)^(+)) and E(2+ 1 ) values. This is in contrast to the sudden onset in even-even Zr, Mo, and Sr isotopes. Our objective was to complete the systematics by determining the B(E2; 2+ 1 → 0+ 1 ) va...
