Cerium pentaphosphate,CeP5O14,is an ultrafast scintillator,which has a uv-emission band with an extremely short lifetime (about r1 = 12nsec.).Ce3 + in cerium pentaphosphate has a broad uv-absorption band.So it can be used as sensitization ion. We have investigated a new crystalline luminescence material, CeP5O14:Mn, which can emit strong green-yellow light.A series of CeP5O14:Mn crystals were grown from phosphoric acid by the evaporation solution method. The usual experimental conditions are as follows:The manganese carbonate (purity:A.R.) is added to a gold crucible, in which G.R.-grade commercial orthophosphoric acid, H3PO4, containing 15% by weight of water, is filled. As the manganese carbonate has been dissolved completly, the cerium oxide (purity:99.99%) is added into the solution.This mixture is heated in the crucible to about 250℃ and kept for about two days until the excess water has evaporated and the cerium oxide has dissolved. Subsequently the temperature is raised to about 550℃. After a week the crucible is taken out and the mother liquor is poured out of the crucible. The crystals are rinsed in hot water repeatedly. The CeP5O14:Mn crystals, colourless or with a pale yellow colour could be obtained.CeP5O14:Mn crystal compositions were determined by chemical analysis. No obvious change in Ce% content was observed when Mn% content was small. The structure of CeP5O14:Mn crystal was determined.When the content of Mn% in the crystal was low, the crystal structure of CeP5O14:Mn was the same as that of CeP5O14, both belong to the monoclinic system, space group P21/c. Some lattice parameters of CeP5O14 :Mn were calculated by a computer. The results are shown in table 1.The CeP5O14:Mn crystals emit strong green-yellow light when they were excited by 254nm ultraviolet light.The luminescence intensity increases with the increase of Mn% content. CeP5O14 emits ultraviolet light and no luminescence of LaP5O14 :Mn was observed.The results indicate the energy transfer from Ce3+ to Mn2 + exists.The absorption spectra show that CeP5O14 has a strong absorption peak in the wavelength range of 255-320nm, LaP5O14:Mn has a weak peak at 290nm, and when CeP5O14 is doped with manganese, the absorption peaks move toward the shorter wavelength side and a split of absorption peak were observed (fig.1).The excitation spectra of CeP5O14:Mn has been measured. The excitation peak of CeP5O14:Mn is the same as that of CeP5O14. The intensity of the strongest peak shown at 302nm decreases as the content of Mn% increases.The emission spectra of CeP5O14:Mn under excitation of 302nm show three groups of emission peaks at about 332, 545, and 665nm. But CeP5O14 has only one group peaking at about 332nm, so the other two groups peaking at 545 and 665nm are considered as emission of manganese ion.An interesting phenomenon was observed, as the content of Mn% was increased, the emission intensity at 545nm was increased, while that at 685nm was decreased. As shown in fig,4 and fig,5,

The pionic two body decay process of the proton is discussed in the SU(5) grand unification theory by using the field-current relation of the composite particle and the soft pion approximations. We connect the proton decay process with the J/(?)→p(?) decay amplitude and determine the wavefunction at the origin from the experimental value of the decay rate J/(?)→P(?), hence we can obtain the value of the proton decay lifetime.

The pionic two body decay process of the proton is discussed in the SU(5) grand unification theory by using the field-current relation of the composite particle and the soft pion approximations. We connect the proton decay process with the J/(?)→p(?) decay amplitude and determine the wavefunction at the origin from the experimental value of the decay rate J/(?)→P(?), hence we can obtain the value of the proton decay lifetime. In order to estimate the uncertainty of the proton decay lifetime due to the proton wavefunetion at the origin, the lower bound of it is analysed by using an interesting model. If taking A(?)= 200 MeV, it will be a serious test for the minimal SU(5) grand unified gauge theory. It should be noted that this method which connect the proton decay process with other relavant processes will be very useful to determine the proton decay lifetime.

本文采用了复合粒子场流关系式和软π介子近似等技巧,在SU(5)大统一规范理论里讨论了质子两体衰变,如p→π~0e~+等。我们把它与J/φ→p(?)衰变振幅联系起来,这样就可由J/φ→P(?)衰变宽度的实验值给出质子零点波函数值,从而确定质子衰变寿命的大小。为了估计质子零点波函数给质子寿命带来的不确定性,利用一个具体模型分析了零点波函数可能的下限。如果取∧_(?)=200 MeV,这将是对简单的SU(5)大统一规范理论的一个严峻考验。值得注意的是本文提供了一种把质子衰变过程与其它相关过程联系起来的方法,这对于确定质子衰变寿命来讲是很有用的。

Molecular beam experiment plays an important role in molecular reaction dynamics. In molecular beam experiment the density of the scatteredproducts is at best the same order of magnitude as the density of the backgr-ound in tne detector chamber, and typically is several orders of magnitudeless. Apart from the use of modern high intensity supersonic beam source, beammodulation, ion-electron multipliers, differential pumping of the detectorand counting techniques to increase the ratio of signal to noise of the detect-or, the improvement of the ionizer itself is also an interesting project. Besi-des, the time of flight of the products is one of the main parameters in theinvestigation of energy distribution during the reaction. thetefore the resoluti-on of the ionizer should be as higk as possible in order to measure the timeof flight accuratelly. A new design of high resolution ionizer is described. Ac-cording to the experimental results, the sensitivity and the resolution of thenew ionizer is Ligher tan that of the Brink's ionizer.

分子束实验在微观动力学的研究中占有重要的位置。在这种实验中,进入探测器的产物往往比探测器中的本底还要低好几个数量级。因此除了采用高强度的超声分子束源,分子束的调制,离子、电子倍增器,分级排气探测器及计数技术等手段来提高信噪比外,改进离子源的本身也是一项很重要的工作。另外,为了能精确测得产物的飞行速度以分析反应过程中的能量分配,还要求离子源具有高的分辨率。本文叙述了一种新设计的高分辨率离子源。实验结果表明,新型离子源的分辨率和灵敏度均优于Brink型离子源。
