The combination–elimination reaction CH 3 + CF → † 2 HF has been studied in a fast-flow system. Infrared chemiluminescence arising from the product observed vibrational levels v = 1–4, and relative rate constants, k(v), have obtained for formation these levels. A study also made of Hg*(6 P 1 ) CHCF Hg(6 S 0 ), which found to produce vibrationally-excited HF. Relative constants k(v) 1–4 obtained. It appears that channelling potential energy into vibration, course elimination step, is more...
Muon spin relaxation/rotation/resonance ( $$\varvec{\mu \textrm{SR}}$$ ) method is one of the most effective experimental methods and has been used in many fields such as material science, chemical, bioscience since 1970s. For next elevation , we developed positron detectors that have a spatial resolution them trackers so could construct an image sample. Demonstrative experiments were performed at TRIUMF sample was successfully reconstructed.
Electronic-to-vibrational transfer has been observed for the process Hg* (6(3)P(1,0)) + HF(upsilon=0) ? Hg(6(1)S(0)) HFdagger(upsilon=1-6). (The asterisk symbolizes electronic excitation, dagger indicates vibrational excitation.) The observations were made by recording ir emission from HFdagger(v=1-6). A set of relative rate constants k(upsilon) obtained stationary-state concentrations N(upsilon). decrease rapidly with increasing upsilon, up to upsilon = 6. From a comparison total HF...
The muon spin rotation/relaxation/resonance ( $$\varvec{\mu }$$ SR) spectroscopy is widely used as a unique tool for probing magnetic properties in materials. We aim to enhance this method by incorporating imaging functionality. In study, we conducted an experiment using new device that utilizes positron tracking from decays assess the reliability of and its positional resolution. As result, have demonstrated image depicting hole with diameter 5 mm could be reconstructed.
Positron annihilation lifetime spectroscopy (PALS), which is recognized as one of the major analytical methods positron spectroscopy, can directly detect information related to size vacancy-type defects from values. PALS measurements performed under high background radiation have been previously reported. It well known that coincidence techniques such age–momentum correlation (AMOC) are effective for reduction, but count rates decline significantly. In this study, a preliminary experiment...
Charge-changing cross sections $${\sigma _{cc}}$$ for mirror nuclei pair, $$^{22}$$ Ne and Mg, on carbon proton targets were measured at 120 MeV/nucleon. The experimental _{cc}^{exp.}}$$ compared with Glauber-type calculations using the known density distribution of target projectile. Moreover, assuming perfect charge symmetry, radius Mg was deduced that from isotope shift. We examined possibility charge-changing section as a new method to determine neutron skin thickness.
The charge-changing cross sections $$\sigma _\mathrm{{cc}}$$ of $$^{10\text {-}13}$$ B, $$^{11\text C, and $$^{12,13}$$ N nuclides on multiple targets were measured at the energy about 170 MeV/nucleon. point-proton radii these determined by comparing experimental with Glauber model calculation considering charged-particle evaporation effect. For present results are consistent existing data deduced different methods.
