Rotational Feshbach resonances in the deformed halo nucleus Ne

Shin Watanabe, Shoya Ogawa, Takuma Matsumoto +1

Background: The deformed halo nucleus Ne exhibits unique structural properties arising from the interplay between its halo neutron and the deformation of the Ne core.…

Description of nucleon elastic scattering off Li with the four-body continuum-discretized coupled-channels method

Kazuyuki Ogata, Shoya Ogawa

Background: Neutron reactions off lithium isotopes up to 50 MeV are important for nuclear data science, around the International Fusion Material Irradiation Facility (IFMIF) facili…

Establishing the Ca reaction at 392 MeV under quasi-free scattering conditions

Riku Matsumura, Junki Tanaka, Kazuki Yoshida +80

The reaction offers a direct means to probe preformed -cluster structures in nuclei under quasi-free scattering conditions. Previous studies around 100 MeV provided va…

Systematic analysis of proton- and deuteron-induced one-proton knockout reactions

Hibiki Nakada, Shoya Ogawa, Yoshiki Chazono +1

The ratios of the one-proton knockout cross sections by a deuteron to those by a proton are about 1.5, indicating that using deuteron is more efficient than proton in yielding larg…

Determination of from C breakup reaction within a four-body reaction model

Shoya Ogawa, Tokuro Fukui, Jagjit Singh +1

The astrophysical factor for the B(,)C has indirectly been measured with the proton removal reactions from C, elastic breakup of C off a heavy ta…

Three-body analysis reveals the significant contribution of minor He -wave component in LiHe cross section

Shoya Ogawa, Kazuki Yoshida, Yoshiki Chazono +1

Li is usually treated as an three-body system, and the validity of this picture is important for understanding Li reactions. The (,) reaction is a powerful m…

Systematic analysis of and He breakup reactions

Shoya Ogawa, Shin Watanabe, Takuma Matsumoto +1

Systematic measurement of and He knockout processes is planned. The weakly-bound nature of these nuclei may affect the interpretation of forthcoming knockout reaction data.…

Dineutron in the state of He

Shoya Ogawa, Takuma Matsumoto

We investigate the dineutron in the state of He via analysis of its decay mode by using the complex scaling method. In this letter, we propose the cross section for the…

Investigation of multi-step effects for proton inelastic scattering to the state in He

Shoya Ogawa, Takuma Matsumoto, Yoshiko Kanada-En'yo +1

Multi-step effects between bound, resonant, and non-resonant states have been investigated by the continuum-discretized coupled-channels method (CDCC). In the CDCC, a resonant stat…

Investigation of contributions of the resonance in He via analysis of He(, )

Shoya Ogawa, Takuma Matsumoto

We investigate the contribution of the resonance in He to observables via analysis of the He() reaction by using the continuum-discretized coupled channel…

Microscopic optical potentials including breakup effects for elastic scattering

Shoya Ogawa, Ryo Horinouchi, Masakazu Toyokawa +1

We construct a microscopic optical potential including breakup effects for elastic scattering of weakly-binding projectiles within the Glauber model, in which a nucleon-nucleus pot…
