In a recent breakup-reaction experiment using Be12 beam at 29 MeV/nucleon, the 0+ band head of expected He4+He8 molecular rotation was clearly identified about 10.3 MeV, from which large monopole matrix element 7.0±1.0 fm2 and cluster-decay width were determined for first time.

The SEEDSTICK transcription factor is important for flower and seed development, but the underlying molecular mechanisms remain unclear in cotton. In this study, we identified cloned two STK homolog genes upland cotton, an economically valuable cultivated crop. Phylogenetic sequence analyses showed that C-terminus of both GhSTKs had a conserved -DJJILHLG amino acid GhSTK1 GhSTK2 were very similar to GaAGL11 GrAGL11, respectively. Quantitative real-time PCR analysis revealed highly expressed...
An inelastic excitation experiment was performed with a $^{12}\mathrm{Be}$ beam at 29 MeV/u on carbon target. New resonances close to the respective cluster separation thresholds were observed in for $^{4}\mathrm{He}+^{8}\mathrm{He}$ and $^{6}\mathrm{He} + ^{6}\mathrm{He}$ decay channels, confirming previously proposed molecular rotational bands. Using model-independent angular correlation analysis, ${0}^{+}$ spin parity is assigned remarkably large peak 10.3 MeV $^{4}\mathrm{He}...

Background: For the deeply bound one-nucleon removal at intermediate energies using a $^{9}\text{Be}$ or $^{12}\text{C}$ target, strong reduction of cross section was observed relative to prediction eikonal theoretical model. The large disagreement has not been explained and systematic trend is inconsistent with results from transfer reactions. recently asymmetric parallel momentum distribution knockout residue indicates significant dissipative core-target interaction in reaction composite...
