被引用回数:6 パーセンタイル:44.13(Physics, Nuclear)The levels in Sn populated from the
decay of
In isomers were investigated at the ISOLDE facility of CERN using the newly commissioned ISOLDE Decay Station. The lowest 1/2
state and the 3/2
ground state in
Sn are expected to have configurations dominated by the neutron
(
=0) and
(
=2) single-particle states, respectively. Consequently, these states should be connected by a somewhat slow
-forbidden
transition. Using fast-timing spectroscopy we have measured the half-life of the 1/2
315.3-keV state,
= 19(10) ps, which corresponds to a moderately fast
transition. Shell-model calculations using the CD-Bonn effective interaction, with standard effective charges and
factors, predict a 4-ns half-life for this level. We can reconcile the shell-model calculations to the measured
value by the renormalization of the
effective operator for neutron holes.

被引用回数:23 パーセンタイル:79.89(Physics, Nuclear)A smooth onset of collectivity in Kr has been determined from reported
and E(2
) 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
value in
Kr, which was produced by cold-neutron-induced fission of
U. The lifetime of the 2
state in
Kr was measured via the electronic
timing technique using the EXILL and FATIMA spectrometers. Based on the measured mean lifetime of
= 15(10) ps, the
value of 13
W.u. in
Kr is determined for the first time and the smooth onset of deformation in the even-even Kr isotopes beyond neutron number N=50 is confirmed.
