Deformation and shape coexistence in $^{66,70}$Ni and $^{69,71}$Cu nuclei near N $=$ 40

ORAL

Abstract

New data will be presented for the levels of $^{66,70}$Ni and $^{69,71}$Cu that extend some of the previously indicated features of deformation and shape coexistence in this region. [R. Broda et al., Phys. Rev. C 86, 064312 (2012)] Excited states in these nuclei were populated through multinucleon-transfer reactions using $^{70}$Zn beams provided by the ATLAS facility at ANL. In particular, possible structure associated with the 0$_{3}^{+}$ level in $^{66}$Ni will be discussed. New levels will be presented in $^{69,71}$Cu that extend the 2-particle-1-hole structures to higher energy and spin. [C. J. Chiara et al., Phys. Rev. C 85, 024309 (2012)] Data will be presented that support the placement of a new level in $^{70}$Ni at 2912 keV with a spin and parity of (5-).
