4. Investigating neutron-proton pairing in sd-shell nuclei via (p,3He) and (3He,p) transfer reactions

Dr Jenny Lee (The University of Hong Kong)

Oral contribution

Pairing correlations, influencing almost every feature of ground and low-lying states in nuclei, lie at the heart of nuclear physics. Understanding the mechanism of neutron-proton (np) pairing in N=Z nuclei has been a long-sought goal in nuclear structure since the early sixties. Despite large efforts in both theoretical and experimental studies, the fundamental nature and the interplay...

30. Transfer reactions induced with 56Ni: np pairing and N=28 shell closure

Ms Anastasia Georgiadou (Institut de Physique Nucléaire d'Orsay (IPN))

Oral contribution

An efficient way to explore the nuclear structure is the effective use of transfer reactions. Two different physical aspects are being investigated with the use of transfer reactions on 56Ni, which is a N=Z unstable doubly magic nucleus.

(i)To probe the gap of N=28, we study the spectroscopy of the N=29 and N=27 isotones by the (d,t), (p,d) and (d,p) one nucleon transfer reactions on 56Ni...

73. Investigating excitation and nucleon correlation in 8He using reactions with a solid hydrogen target

Matthias Holl (Saint Mary's University / TRIUMF)

Oral contribution

The nucleus 8He is the most neutron-rich nucleus known. Its structure, consisting of a 4He core surrounded by four neutrons makes it an ideal case to study phenomena in highly neutron-proton asymmetric systems and neutron correlations at the nuclear surface.
The effects of the valence neutrons were investigated experimentally using proton elastic and inelastic scattering of 8He at the IRIS...

59. Total cross sections of reactions 6,8He+28Si, 9,11Li+28Si and role of neutron rearrangement

Prof. Viacheslav Samarin (Joint Institute for Nuclear Research)

04/06/2018, 16:09

Oral contribution

It is well known that neutron rearrangement may play an important role in nuclear reactions. The aim of this work is the investigation of the reactions with light nuclei having different external neutron shells. A series of experiments on measurement of total cross sections for reactions 4,6,8He + Si and 6,7,9,11Li + Si in the beam energy range 5–50 AMeV was performed at Flerov Laboratory of...

55. Probing the pn correlation in nuclei via the (p,pd) reaction

Yoshiki Chazono (Research Center for Nuclear Physics, Osaka University)

Oral contribution

Deuteron is the only binding system which consists of two nucleons (a proton and a neutron) in free space.
Recently, theoretical calculation with density functional theory (DFT) suggests that the "deuteron-like" pn pair exists in nuclei.
We propose the (p,pd) reaction to probe the pn pair, and discuss how the (p,pd) cross section reflects the pn pair inside the target nucleus.
We calculate...
