Measurement of Doppler effects in cryogenic buffer-gas cell
Ayami Hiramoto, Masaaki Baba, Katsunari Enomoto +5
Buffer-gas cooling is a universal cooling technique for molecules and used for various purposes. One of its applications is using molecules inside a buffer-gas cell for low-tempera…
Low- transitions in band of buffer-gas-cooled CaOH
Yuiki Takahashi, Masaaki Baba, Katsunari Enomoto +5
Calcium monohydroxide radical (CaOH) is receiving an increasing amount of attention from the astrophysics community as it is expected to be present in the atmospheres of hot rocky…
Hyperfine-structure-resolved laser spectroscopy of many-electron highly charged ions
Naoki Kimura, Priti, Yasutaka Kono +6
Hyperfine-structures of highly charged ions (HCIs) are favourable spectroscopic targets for exploring fundamental physics as well as nuclear properties. Recent proposals of HCI ato…
High-resolution spectroscopy of buffer-gas-cooled phthalocyanine
Yuki Miyamoto, Reo Tobaru, Yuiki Takahashi +5
For over five decades, studies in the field of chemical physics and physical chemistry have primarily aimed to understand the quantum properties of molecules. However, high-resolut…
Status of the Laser Spectroscopy and Merged-beam Experiments at RICE
Y. Nakano, R Igosawa, S. Iida +9
Recently, we reported the commissioning of the new cryogenic ion storage ring RICE, which demonstrated potential capabilities for the precise studies of molecular structures and re…
Superfluorescence, free-induction decay, and four-wave mixing: propagation of free-electron laser pulses through a dense sample of helium ions
James R Harries, Hiroshi Iwayama, Susumu Kuma +9
We report an experimental and numerical study of the propagation of free-electron laser pulses (wavelength 24.3 nm) through helium gas. Ionisation and excitation populates the He$^…
Simultaneous measurements of super-radiance at multiple wavelengths from helium excited states: (I) Experiment
Kyo Nakajima, James R. Harries, Hiroshi Iwayama +8
In this paper, we report the results of measurements of the intensities and delays of super-radiance decays from excited helium atoms at multiple wavelengths. The experiment was pe…
Observation of coherent two-photon emission from the first vibrationally-excited state of hydrogen molecules
Yuki Miyamoto, Hideaki Hara, Susumu Kuma +10
In this paper, we describe an experiment which was conducted to explore the macro-coherent amplification mechanism using a two-photon emission process from the first vibrationally-…
I molecule for neutrino mass spectroscopy: ab initio calculation of spectral rate
Motomichi Tashiro, Masahiro Ehara, Susumu Kuma +4
It has recently been argued that atoms and molecules may become good targets of determining neutrino parameters still undetermined, if atomic/molecular process is enhanced by a new…
Neutrino Spectroscopy with Atoms and Molecules
Atsushi Fukumi, Susumu Kuma, Yuki Miyamoto +12
We give a comprehensive account of our proposed experimental method of using atoms or molecules in order to measure parameters of neutrinos still undetermined; the absolute mass sc…
Intense pulsed helium droplet beams
Mikhail N. Slipchenko, Susumu Kuma, Takamasa Momose +1
Pulsed (30 - 100 microseconds) nozzle beams have been used to generate helium droplets (<N> = 10^4-10^5). The dependence of the beam intensity and the mean droplet size on the sour…
