Nitric oxide （NO） is increasingly being used in medical treatments of high blood pressure, acute respiratory distress syndrome and other illnesses related to the lungs. Currently a NO inhalation system consists of a gas cylinder of N2 mixed with a high concentration of NO. This arrangement is potentially risky due to the possibility of an accidental leak of NO from the cylinder. The presence of NO in the air leads to the formation of nitric dioxide （NO2）, which is toxic to the lungs. Therefore, an on-site generator of NO would be highly desirable for medical doctors to use with patients with lung disease. To develop the NO inhalation system without a gas cylinder, which would include a high concentration of NO, NAmIHIRA et al have recently reported on the production of NO from room air using a pulsed arc discharge. In the present work, the temperature of the pulsed arc discharge plasma used to generate NO was measured to optimize the discharge condition. The results of the temperature measurements showed the temperature of the pulsed arc discharge plasma reached about 10,000 K immediately after discharge initiation and gradually decreased over tens of microseconds. In addition, it was found that NO was formed in a discharge plasma having temperatures higher than 9,000 K and a smaller input energy into the discharge plasma generates NO more efficiently than a larger one.

Chinese Physics Letters 2004年第7期21卷 1243-1246页

作者： SONGLi-Tao ZHOUXiao-Hong ZHANGYu-Hu GUOYing-Xiang SUNZhi-Yu m.Oshima T.Toh A.Osa m.Koizumi J.Katakura Y.Hatsukawa m.matsuda m.Sugawara 1nstituteofmodernPhysics ChineseAcademyofSciencesLanzhou730000 JapanAtomicEnergyResearchInstitute TokaiIbaraki319-1195Japan ChibaInstituteofTechnology NarashinoChiba275-0023Japan

A standard in-beam γ-spectroscopy experiment for 179Au has been performed via the 149Sm (35Cl, 5n) reaction at beam energies of 164–180meV. Based on the analysis of the experimental results, a rotational band built on the 1/2[660](πi13/2) proton intruder orbital is established for 179Au for the first time. Systematic properties of the 1/2[660](i13/2) band in odd-A Au nuclei are discussed, and the evolution of bandhead energy and deformation with changing neutron number are revealed.

High-spin states in 178'180Ir have been studied via the 152'154Sm(31P,5nγ)reactions through excitation functions,x-γandγ-γ-t coincidence measurements.A doubly decoupled band has been identified in each of the *** level spacings for such structures in odd-odd ^(178-186)Ir have been inspected and thus a regular level staggering as a function of the neutron number is *** particular phenomenon may be associated with bandmixing at lower excitation energies.

Search for Signature Inversion in the πi_(13/2) vi_(13/2) Band in Odd-Odd ^(178I)r

The search for the ri_(13/2) vi_(13/2 ) band in ^(178)Ir has been conducted through the ^(152)Sm(^(31) P, 5nγ)^( 178)Ir reaction and the excitation functions, x-γ and γ-γ-t coincidence measurements. Five rotational bands have been newly identified. The low-spin signature inversion in the πi13/2 vi13/2 band has been confirmed by the observations of linking transitions and signature crossing at I = 25.5 h. The inversion phenomenon in rh11/2 vi_(13/2), rh9/2 vi_(13/2) and ri_(13/2) vi13/2 structures in ^(178)Ir provides a unique testing ground for different theoretical interpretations.

High spin states in 80Rb were studied via the 65Cu+19F, 66Zn+18O and 68Zn+16O reactions. The 75-meV 19F, 76-meV 18O and 80-meV 16O beams were provided by the CIAE HI-13 Tandem accelerator and the JAERI Tandem accelerator. The prompt γ-γ coincidence and the directional correlation from oriented nuclei (DCO) were measured by the detector arrays in CIAE and JAERI. Twenty-three new states with 28 new transitions have been assigned to 80Rb. The states were observed up to spins of 20+ and 22− in the α = 0 branch for the positive and negative parity yrast bands respectively. The negative parity non-yrast bands were significantly extended up to spins of 22− and 15−. The band crossings with frequencies 0.51meV and 0.61meV in the α = 0 cascade were observed for the first time. The signature splitting was observed in both negative parity bands. The signature inversions at spins of about 7 and 15 were observed.
