The structure of the doubly magic 
Sn
has been investigated at the ISOLDE facility at CERN, populated both by the 
-decay of In and --delayed neutron emission of 
In. The level scheme of Sn is greatly expanded with the addition of 68 
-ray transitions and 17 levels. The identification of particle-hole multiplets both for protons and neutrons and the transition rates connecting different particle-hole configurations may provide input on the two-body matrix elements and single-particle states for state-of-the-art calculations.

被引用回数：3 パーセンタイル：35.18(Physics, Nuclear)Excited states in Sn were investigated through the decay of In at the ISOLDE facility. The ISOLDE Resonance Ionization Laser Ion Source (RILIS) provided isomer-selective ionization for In, allowing us to study separately, and in detail, the -decay branch of In 
= (9/2
) ground state and its = (1/2
) isomer. Thanks to the large spin difference of the two -decaying states of In, it is possible to investigate separately the lower and higher spin states in the daughter, Sn, and thus to probe independently different single-particle and single-hole levels. We report here new transitions observed in the decay of In, including those assigned to the deexcitation of the neutron-unbound states.

被引用回数：19 パーセンタイル：13.28(Instruments & Instrumentation)A highly efficient array of high-purity germanium (HPGe) detectors was developed and operated at the cold neutron beam facility PF1B of the Institut Laue-Langevin (ILL) to carry out nuclear structure studies, via measurements of -rays following neutron-induced capture and fission reactions. The setup consisted of a collimation system producing a pencil beam with a thermal capture equivalent flux of about 10
ns
cm
at the target position and negligible neutron halo. The target was surrounded by an array of eight to ten anti-Compton shielded EXOGAM Clover detectors, four to six anti-Compton shielded large coaxial GASP detectors and two standard Clover detectors. For a part of the campaign the array was combined with 16 LaBr
:(Ce) detectors from the FATIMA collaboration.

被引用回数：5 パーセンタイル：47.02(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.
