Generation of Twisted Gamma-Rays via Two-Photon Transition
Motomichi Tashiro, Noboru Sasao, Minoru Tanaka
We present a new and efficient method of generating twisted gamma rays utilizing highly accelerated helium-like ions; they are excited to a chosen state by irradiating two optical…
Macro-coherent radiative emission of neutrino pair between parity-even atomic states
M. Tashiro, B. P. Das, J. Ekman +3
A new scheme to determine the neutrino mass matrix is proposed using atomic de-excitation between two states of a few eV energy spacing. The determination of the smallest neutrino…
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…
Auger decay of molecular double core-hole state
Motomichi Tashiro, Kiyoshi Ueda, Masahiro Ehara
We report on theoretical Auger electron kinetic energy distribution originated from sequential two-step Auger decays of molecular double core-hole (DCH) state, using CH4, NH3 and H…
Double core-hole electron spectroscopy for open-shell molecules: theoretical perspective
Motomichi Tashiro, Masahiro Ehara, Kiyoshi Ueda
We have theoretically investigated the double core-hole (DCH) states of the open-shell molecules and examined the possibility of DCH spectroscopy by means of X-ray two-photon photo…
Molecular double core-hole electron spectroscopy for chemical analysis
Motomichi Tashiro, Masahiro Ehara, Hironobu Fukuzawa +4
We explore the potential of double core hole electron spectroscopy for chemical analysis in terms of x-ray two-photon photoelectron spectroscopy (XTPPS). The creation of deep singl…
