The 9Be(32Ar, 31Ar)X reaction, leading to the 5/2+ ground state of a nucleus at the proton drip line, has a cross section of 10.4(13) mb at a beam energy of 65.1 MeV/nucleon. This translates into a spectroscopic factor that is only 24(3)% of that predicted by the many-body shell-model theory. We introduce refinements to the eikonal reaction theory used to extract the spectroscopic factor to clarify that this very strong reduction represents an effect of nuclear structure. We suggest that it reflects correlation effects linked to the high neutron separation energy (22.0 MeV) for this state. 相似文献

Within their working range the inorganic glasses can be regarded as Newtonian liquids. Their flow behaviour during the extrusion process is therefore generally in good agreement with the Hagen-Poiseuille law, if the boundary condition of a stagnant glass layer at the die wall is fullfilled. 相似文献

We measured the excitation function for 13O + p elastic scattering to obtain data on the unknown 14F nucleus. The ground state and several low-lying excited states in 14F were observed and spin/parity assignments were made. 14F appears to be much less unstable than was predicted. We compare theoretical predictions for the 14F level scheme with the experimental results. 相似文献

Genetic variation forms the basis for diversity but can as well be harmful and cause diseases, such as tumors. Structural variants (SV) are an example of complex genetic variations that comprise of many nucleotides ranging up to several megabases. Based on recent developments in sequencing technology it has become feasable to elucidate the genetic state of a person’s genes (i.e. the exome) or even the complete genome. Here, a machine learning approach is presented to find small disease-related SVs with the help of sequencing data. The method uses differences in characteristics of mapping patterns between tumor and normal samples at a genomic locus. This way, the method aims to be directly applicable for exome sequencing data to improve detection of SVs since specific SV detection methods are currently lacking. The method has been evaluated based on a simulation study as well as with exome data of patients with acute myeloid leukemia. An implementation of the algorithm is available at https://github.com/lenz99-/svmod. 相似文献
