Two-proton emission as source of spin-entangled proton pairs

Tomohiro Oishi, Masaaki Kimura

We show that a two-proton emitter with a diproton-correlated initial state can act as a source of spin-correlated proton pairs. Using a time-dependent three-body model, we investig…

One-proton emission of Sb and its sensitivity to proton-neutron interaction

Tomohiro Oishi, Masaaki Kimura, Lorenzo Fortunato

One-proton emission from the Sb nucleus is discussed, assuming an inert Sn core and the valence proton and neutron. There are experimentally measured bound states i…

Analytic continuation in coupling constant applied to two-proton emitters

Tomohiro Oishi, Masaaki Kimura

For quantum meta-stable problems with three particles, the Be and Ne nuclei as two-proton () emitters provide a testing field. Considering the complexity of many-b…

Interference of resonances in two-proton emission of Ne

Tomohiro Oishi, Masaaki Kimura

We investigate the two-proton () emission from Ne with the time-dependent O three-body calculations. Two resonances are suggested to participate. For…

Uncovering the sign of nuclear deformations: Determination of prolate or oblate shape via low-energy inelastic scattering

Shin Watanabe, Yoshiki Suzuki, Masaaki Kimura +1

Background: Understanding nuclear shape is a crucial problem in nuclear physics. In particular, determining the sign of quadrupole deformation, i.e., whether prolate or oblate, rem…
