Single particle motion in isomeric states
Invited Presentation
Decay spectroscopy following projectile fragmentation constitutes one of the most sensitive methods of studying exotic nuclei. It enables nuclear structure investigations for species produced with very low yields (few nuclei an hour).
Exotic nuclei were synthesised using relativistic projectile fragmentation. The fragments were separated and unambiguously identified event-by-event using the...

Single particle motion in isomeric states
Presentation
We are performing the experimental studies on high-spin isomers [1].
These isomers have been reported in $N$=83 isotones with $Z$=60$-$67.
The spins of these isomers are 49/2$^+$ and 27$^+$ for odd and odd-odd
nuclei, respectively. Their shapes were known to be oblate with a deformation
parameter $\beta$$\sim$$-$0.2. These isomerism were understood to be
caused by the sudden shape...

The recent observation of high-spin isomers in Neodymium nuclei around the
N=82 shell closure triggered new experimental investigations aiming to the
identification of other similar isomers in the neighboring nuclei. The
results of lifetime measurements for the 6-qp 20+ isomer in 140-Nd and for
the 3-qp isomer above the 19/2+ state in 139-Nd represent a strong support
to the cranked...
