Excited states in Si38,40,42 nuclei have been studied via in-beam γ-ray spectroscopy with multinucleon removal reactions. Intense radioactive beams of S40 and S44 provided at the new facility of the RIKEN Radioactive Isotope Beam Factory enabled γ-γ coincidence measurements. A prominent γ line observed with an energy of 742 keV in Si42 confirms the 2 + state reported in an earlier study. Among the γ lines observed in coincidence with the 2 +→0 + transition, the most probable candidate for the transition from the yrast 4 + state was identified, leading to a 41+ energy of 2173 keV. The energy ratio of 2.93 between the 21+ and 41+ states indicates well-developed deformation in Si42 at N=28 and Z=14. Also for Si38,40 energy ratios with values of 2.09 and 2.56 were obtained. Together with the ratio for Si42, the results show a rapid deformation development of Si isotopes from N=24 to N=28. © 2012 American Physical Society.

Modern philosophy is divided, apparently. The two apparent divisions are commonly referred to as “Analytic” and “Continental” (Prado). The former division is often seen as Kantian, ahistoricist, scientific, and logical; the latter division is often seen as Hegelian, historicist, conversational, and rhetorical (Rorty). In this paper, we attempt to use the principles of experimental philosophy and comparative computational techniques against a corpus of self-identified “analytic” and “continental” texts in order to test various hypotheses about the analytic/continental divide from the philosophical literature: some hypotheses are supported, some opposed, and others left open to further research.
