TLDR
Coincidence measurements between the isolated isotope and prompt gamma radiation allowed the identification of decays from low-lying states at E = 290 and 828 keV which indicate that /sup 80/Zr has an extremely large quadrupole deformation.Abstract:
The very neutron-deficient isotope /sup 80/Zr was produced in the reaction /sup 24/Mg(/sup 58/Ni, 2n)/sup 80/Zr at 190 MeV with a cross section of sigma = 10 +- 5 ..mu..b and was identified with the Daresbury Recoil Separator. The observation reflects a fiftyfold increase in sensitivity for in-beam spectroscopy of exotic nuclei. Coincidence measurements between the isolated isotope and prompt gamma radiation allowed the identification of decays from low-lying states at E = 290 and 828 keV which indicate that /sup 80/Zr has an extremely large quadrupole deformation of ..beta../sub 2/approx. =0.4.read more

TL;DR: In this paper, the influence of nuclear structure on the rp-process between Ge and Sn in various scenarios was investigated and it was shown that 2p-capture reactions accelerate the reaction flow into the Z greater than or equal to 36 region considerably.

Nuclei beyond the proton drip-line
P. J. Woods,C. N. Davids +1 more
TL;DR: The proton drip-line defines the limit at which nuclei become unbound to the emission of a proton from their ground states as discussed by the authors, and thus limits the ability of nuclei to survive long enough to be detected.

Exotic nuclei explored at in-flight separators
TL;DR: In the last decade, in particular, this field has expanded rapidly with the advent of the new-generation (3rd-generation) in-flight-separator facility, the RI-beam Factory (RIBF) at RIKEN that was commissioned in 2007 as mentioned in this paper.

TL;DR: In this article, the authors calculate the low-lying strength of the nickel isotopes using several theoretical approaches and show that the transition to the first 2.5 MeV state exhausts only a fraction of the lowlying strength, while the remainder is mainly collected in the group of states lying above 4 MeV.
