Influences on the triple alpha process beyond the Hoyle state

7 pags., 3 figs. -- International Symposium on Nuclear Astrophysics - Nuclei in the Cosmos - IX, 25-30 June 2006, CERNThe triple alpha process is studied using indirect methods. The beta decays of 12N and 12B are used to probe the triple alpha continuum of 12C. Different independent breakup channels are identified, consistently showing that the 10 MeV strength is dominated by a 0+ state interfering with the Hoyle state ghost. The 13–14 MeV region on the other hand is dominated by a 2 + state

Observation of γ-delayed 3α breakup of the 15.11 and 12.71 MeV states in 12C

6 pags., 4 figs., 2 tabs. -- PACS:27.20.+n25.55.Hp23.20.-g29.85.-cThe reactions 10B (3He, p α α α) at 4.9 MeV and 11B (3He, d α α α) at 8.5 MeV have been used to investigate the γ decay of states in 12C. By measuring the four-body final state in complete kinematics we are able to detect γ transitions indirectly. We find γ transitions from the 15.11 MeV state in 12C to the 12.71, 11.83, 10.3 and 7.65 MeV states followed by their breakup into three α particles. The relative γ-ray branching ratios obtained are (1.2 ± 0.3), (0.32 ± 0.12), (1.4 ± 0.2) and (4.4 ± 0.8) %, respectively, with the remaining (92.7 ± 1.0) % of the γ decays going to the bound states. We obtain Γα / Γ = (2.8 ± 1.2) % for the isospin-forbidden α decay of the 15.11 MeV state. From the 12.71 MeV state we find γ transitions to the 10.3 and 7.65 MeV states. The relative γ-ray branching ratios are (0.9- 0.5 + 0.6) and (2.6- 1.2 + 1.6) %, respectively, with the remaining (96.6- 1.3 + 1.7) % of the γ decays going to the bound states. Finally, we discuss the relation between the β decay of 12N and 12B to states in 12C and the γ decay of the 15.11 MeV analog in 12C to the same states. © 2009 Elsevier B.V.We would like to acknowledge the support of the Spanish CICYT research grant FPA2007-62170 and the MICINN Consolider Project CSD 2007-00042 as well as the support of the European Union VI Framework through RII3-EURONS/JRA4-DLEP (contract number 506065).

The Influence of Banking Relationship on Accounting Conservatism: An Empirical Research in Chinese A-Share Stock Market

本文用2007-2010年中国非金融保险行业非ST的A股上市公司的数据，结合我国特殊的制度背景，以代理理论、信息不对称理论和不完全契约为理论基础，用Basu(1997)模型检验银行往来关系与会计稳健性之间的关系。 由于银行和企业之间的信息不对称和存在债务代理冲突，银行对企业稳健性产生需求。银行往来关系是企业与银行超越单纯金融关系的密切关系，会在企业和银行之间产生一种信息交换机制。本文用银往来银行的数目来进行度量分析了银行往来关系对会计稳健性的影响。进而本文分析了四大国有控股商业银行往来关系与会计稳健性之间的关系。 银行和企业的信息交换，会缓解银行和企业的代理冲突和信息不对称问题，实证发现银...The paper adopts Basu(1997) model to check the relationship between bank intercourse and accounting conservatism with A shares excluding financial or ST companies in the background of China’s special system based on principal-agent theory, asymmetric information and imperfect contract theory. Due to the asymmetric information and conflict of the bank with enterprises, the bank requests accoun...学位：会计硕士院系专业：管理学院会计系_会计硕士学号：1842009115057

Scattering of

In order to study the dynamics of 11Li and 9Li beams in a strong electric field at energies around the Coulomb barrier, we measured at the ISACII-TRIUMF Facility the angular distribution of elastic and inelastic scattering of 11Li+208Pb at 24.2 and 29.7 MeV and 9Li+208Pb at 24, 29.5 and 33 MeV laboratory energies. We present here the first determination of the angular distribution of the cross section of 9Li+208Pb. The results are compared with theoretical calculations using the double-folding São Paulo Potential (SPP) for the real part and a for the imaginary part a Woods-Saxon potential. A good overall agreement is obtained
