The impact of shadow banking on the implementation of Chinese monetary policy
This paper empirically analyses the relationship between the shadow banking system and implementation of monetary policy in China using the VECM methodology. We show that an increase in the size of shadow banking sector increases the independence of bank lending from the policies of the People Bank of China. We also find that Shadow Banking works in an asymmetric fashion in that it amplifies increases in the money supply but weakens the effects of restrictive interest rate-based monetary policy decisions
First beta-decay spectroscopy of In-135 and new beta-decay branches of In-134
The beta decay of the neutron-rich In-134 and In-135 was investigated experimentally in order to provide new insights into the nuclear structure of the tin isotopes with magic proton number Z = 50 above the N = 82 shell. The beta-delayed gamma-ray spectroscopy measurement was performed at the ISOLDE facility at CERN, where indium isotopes were selectively laser-ionized and on-line mass separated. Three beta-decay branches of In-134 were established, two of which were observed for the first time. Population of neutron-unbound states decaying via. rays was identified in the two daughter nuclei of In-134, Sn-134 and Sn-133, at excitation energies exceeding the neutron separation energy by 1 MeV. The beta-delayed one- and two-neutron emission branching ratios of In-134 were determined and compared with theoretical calculations. The beta-delayed one-neutron decay was observed to be dominant beta-decay branch of In-134 even though the Gamow-Teller resonance is located substantially above the two-neutron separation energy of Sn-134. Transitions following the beta decay of In-135 are reported for the first time, including. rays tentatively attributed to Sn-135. In total, six new levels were identified in Sn-134 on the basis of the beta.. coincidences observed in the In-134 and In-135 beta decays. A transition that might be a candidate for deexciting the missing neutron single-particle 13/2(+) state in Sn-133 was observed in both beta decays and its assignment is discussed. Experimental level schemes of Sn-134 and Sn-135 are compared with shell-model predictions. Using the fast timing technique, half-lives of the 2(+), 4(+), and 6(+) levels in Sn-134 were determined. From the lifetime of the 4(+) state measured for the first time, an unexpectedly large B(E2; 4(+)-> 2(+)) transition strength was deduced, which is not reproduced by the shell-model calculations.Peer reviewe

Detailed spectroscopy of doubly magic Sn-132
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 -transitions and 17 levels observed for the first time
in the decay. The information on the excited structure is completed by
new -transitions and states populated in the -n decay of
In. Improved delayed neutron emission probabilities are obtained both
for In and In. Level lifetimes are measured via the Advanced
Time-Delayed (t) fast-timing method. An interpretation of
the level structure is given based on the experimental findings and the
particle-hole configurations arising from core excitations both from the
\textit{N} = 82 and \textit{Z} = 50 shells, leading to positive and negative
parity particle-hole multiplets. The experimental information provides new data
to challenge the theoretical description of Sn.Comment: 19 pages, 11 figures. Accepted for publication in Phys. Rev.
