What were the highlights of his more recent work (between 2014-2021)?

  • Atomic physics (63.97%)
  • Neutron (38.35%)
  • Isotope (21.82%)

In recent papers he was focusing on the following fields of study:

Atomic physics, Neutron, Isotope, Excited state and Spectroscopy are his primary areas of study. While the research belongs to areas of Atomic physics, Takaharu Otsuka spends his time largely on the problem of Excitation, intersecting his research to questions surrounding Island of inversion. Neutron is a subfield of Nuclear physics that Takaharu Otsuka tackles.

His research integrates issues of Line and State in his study of Nuclear physics. He works mostly in the field of Isotope, limiting it down to concerns involving Atomic nucleus and, occasionally, Quantum and Magnetic monopole. His Excited state study combines topics from a wide range of disciplines, such as Bound state and Molecular physics.

Between 2014 and 2021, his most popular works were:

  • Detailed deposition density maps constructed by large-scale soil sampling for gamma-ray emitting radioactive nuclides from the Fukushima Dai-ichi Nuclear Power Plant accident (191 citations)
  • Quantum Phase Transition in the Shape of Zr isotopes (95 citations)
  • 78 Ni revealed as a doubly magic stronghold against nuclear deformation (54 citations)

In his most recent research, the most cited papers focused on:

  • Quantum mechanics
  • Electron
  • Neutron

Takaharu Otsuka mainly focuses on Atomic physics, Neutron, Spectroscopy, Isotope and Excitation. His studies deal with areas such as Fission and Atomic orbital as well as Atomic physics. His Neutron study deals with the bigger picture of Nuclear physics.

Takaharu Otsuka interconnects Island of inversion and Ground state in the investigation of issues within Spectroscopy. His Isotope study incorporates themes from Quantum phase transition, Neutron number, Hamiltonian and Parity. His SHELL model research focuses on Analytical chemistry and how it connects with Isotopes of potassium.
