利用放射性束68Fe轰击液氢靶引起的敲出反应,研究了极端丰中子核^(63,65,67)Mn的激发态,指认了它们的自旋宇称,建立了这三个原子核的能级纲图。纲图包含11/2^(-)、9/2^(-)和7/2^(-)三个激发态以及5/2^(-)_(g.s.)基态,它们由三条ΔI=1的γ跃迁连接。这种能级结构与K=5/2时强耦合转动带的特征一致。使用改进的LNPS有效相互作用(LNPSm)的大规模壳模型计算能很好地重现观测到的能级。计算表明,^(65,67)Mn的低位激发态都主要包含处于4p-4h的中子组态和1p-1h的质子组态。基于实验结果发现,在吸积中子星壳中,与质量数A=63相关的Urea中微子冷却效果比预期的要强很多,而A=65,67的冷却效果比预期的更弱。

Porous calcium phosphate ceramics were produced by compression molding using a special mold followed by sintering. The porous calcium phosphate ceramics have three-dimensional and penetrated open pores 380-400μm in diacneter spaced at intervals of 200μm. The layers of the linear penetration pores alternately lay perpendicular to pore direction. The porosity was 59%-65% . The Ca/ P molar ratios of the porous calcium phos phate ceramics range from 1.5 to 1.85. A binder cantaining methyl cellulose was most effective for preparing the powder compact among vinyl acetate, polyvinyl alcohol, starch, stearic acid, methyl cellulose and their mixtures . Stainless steel, polystyrene, nylon and bamboo were used as the long columnar dies for the penetrated open pores. When polystyrene, nylon and bamboo were used as the long columnar male dies, the dies were burned oat during the sintering process. Using stainless steel as the male dies with the removal of the dies before heat treatment resulted in a higher level of densification of the calcium phosphate ceramic.
