| 1. | In nuclear fusion, a pair of light nuclei unite (or fuse) together, form a nucleus of a heavier atom . 在核聚变的情况下,一对轻核合并(或聚合)在一起,形成一个较重的原子核。 |
| 2. | In the first place, the fractional decrease in neutron energy per collision is, on the average, greatest for light nuclei . 第一,平均来说原子核愈轻,每次碰撞后中子的能量损失分额就愈大。 |
| 3. | A new model for light nucleus has been developed based on unified hauser - feshbach and exciton model 基于统一的豪泽?费许巴赫理论和激子模型,计算中子诱发轻核反应的新理论已经产生。 |
| 4. | Utilizing this model , the distributions of valence nucleons are calculated for some light nuclei . some new halo or skin states are predicted 利用该模型,计算了一些轻核外层核子的分布,预言了一些尚未发现的晕、皮核态。 |
| 5. | In the reaction processes of light nucleus the pre - equilibrium emissions dominate the reactions mechanism , while the equilibrium state only gives lightly implement even at low neutron incident energies 在轻核反应过程中,预平衡发射在反映机制中占主导地位,平衡态贡献小。 |
| 6. | Similar to the helium burning , the strong gravitational force of the star ignites and controls the carbon burning in the core ; light nuclei fuse into heavier and heavier elements , until iron 情况很像燃烧氦,强大的引力足以在核心燃点起碳,而同时维持星体稳定。核心物质不断聚变为更重的元素,直至成为铁。 |
| 7. | Halo nuclei have been the hot point in the studies of nuclear physics since the discovery of the neutron halo ( or neutron skin ) in the light nuclei , such as " li , near the neutron drip line in the middle of 1980 ' s 自80年代中期~ ( 11 ) li等中子滴线附近轻核的中子晕(或中子皮)被发现以来,晕核一直是核物理研究的一个热点。 |
| 8. | To fit the experimental data the level broadening effect and the energy resolution must be considered . meanwhile , the residual nuclei can decay spontaneously into two clusters or carry out multi - particle break - up process , these are the characteristic for light nucleus reaction 有些反应道可能经由一系列不同的反应过程,或者是两体衰变,或者是两体崩裂过程,甚至发生多体崩裂过程,这些都是轻核反应的特点。 |
| 9. | The results indicate that the effects of the dirac sea states are pronounced in the collective multipole excitations for nuclei , especially on the isoscalar giant modes , but become weaker for light nuclei , while the contributions on the isovector modes are negligible 在核的同位旋标量激发模式中, dirac海负能核子态在不同的共振模式中的贡献程度不一。对于同一种激发模式, dirac海负能核子态的贡献随着核子数的减少而变弱。 |
| 10. | Those investigations have improved one ' s understanding of the structure , formation conditions , reaction mechanisms , and excitation modes of halo nuclei . inl990 ' s it was predicted that besides the ground state of the light nuclei near the drip line , the high isospin excited states may also have halo structure 除滴线附近轻核的基态外,九十年代有人预言稳定核的高同位旋激发态也可能具有晕结构, ~ ( 13 ) c第一激发态和~ 6li第二激发态被列为首选的研究对象。 |
