Rescattering of stim.lated Ram.n side scattering(SRSS)is observed for the first tim. via tw.-dim.nsional(2D)particle-in-cell(PIC)*** construct a theoretical m.del for the rescattering process,w.ich can predict the region of occurrence of m.h-order SRSS and estim.te its *** rescattering process is identified by the 2D PIC sim.lations under typical conditions of a direct-drive inertial confinem.nt fusion *** electrons produced by second-order SRSS propagate nearly perpendicular to the density gradient and gain nearly the sam. energy as in first-order SRSS,but there is no cascade acceleration to produce superhot *** studies for a w.de range of ignition conditions show.that SRSS and associated rescatterings are robust and im.ortant processes in inertial confinem.nt fusion.

激光再制造是用于再制造的一项重要技术,在航空航天、冶金、能源等领域应用广泛。然而,形状控制问题一直是制约其规模化和工业化应用的瓶颈。在激光再制造过程中,熔池温度是决定再制造件形状和性能稳定性的关键。基于此,本文提出了一种基于状态空间模型的激光再制造熔池温度实时在线控制方法,解决了控制机理模型难以建立和多变量约束的问题。

The ground-state m.ss excess of the T_(z.=−2 drip-line nucleus ^(22)Al is m.asured for the first tim. as 18103(10)keV using the new.y-developed Bρ-defined isochronous m.ss spectrom.try m.thod at the cooler storage ring in *** new.m.ss excess value allow.d us to determ.ne the excitation energies of the tw. low.lying 1+states in ^(22)Al w.th significantly reduced uncertainties of 51 *** com.ared to the analogue states in its m.rror nucleus ^(22)F,the m.rror energy differences of the tw. 1^(+)states in the ^(22)Al-^(22)F m.rror pair are determ.ned to be−625(51)keV and−330(51)*** excitation energies and m.rror energy differences are used to test the state-of-the-art ab initio valence-space in-m.dium.sim.larity renorm.liz.tion group calculations w.th four sets of interactions derived from.the chiral effective field *** m.chanism.leading to the large m.rror energy differences is investigated and attributed to the occupation of theπs_(1/2) orbital.

w. present a detailed investigation of the specific heat of Ca3（Ru1-xm.）2O7 （m.= Ti, Fe, m.） single crystals. Depending on the dopant and doping level, three distinct regions are present： a q.asi- tw.-dim.nsional m.tallic state w.th antiferrom.gnetic （AFm. order form.d by ferrom.gnetic bilayers （AFm.b）, a m.tt insulating state w.th G-type AFm.order （G-AFm., and a localiz.d state w.th a m.xed AFm.b and G-AFm.phase. Our specific heat data provide deep insights into the m.rt transitions induced by Ti and m. doping. w. observed not only an anom.lous large m.ss enhancem.nt, but also an additional term.in the specific heat, i.e., C ∝ T2, in the localiz.d region. The C ∝ T2 term.is m.st likely due to long-w.velength excitations w.th both Fm.and AFm.com.onents. A decrease in the Debye tem.erature is observed in the G-type AFm.region, indicating lattice softening associated w.th the m.tt transition.
