DESCRIPTION:Speakers: He Wang ()\nThe short range correlation (SRC)\, is a
  peculiar new phenomenon that is relevant to the most dense part of the nu
 cleus\, as the SRC happens when the nucleon-nucleon pair is close to each 
 other by only about a half of their normal average distance. Due to the He
 isenberg's uncertainty principle\, the SRC nucleons have much higher momen
 tum than the Fermi momentum\, contrary to the conventional\, standard pict
 ure of nuclei where nucleon momenta are limited to the Fermi momentum. To 
 establish a comprehensive understanding of nuclei\, new insights from expe
 rimental and theoretical investigations on SRC are required. \n\nSo far\, 
 the SRC has been studied only for "stable" nuclei. One of the current issu
 es on SRC is how the asymmetry of proton and neutron numbers affect the SR
 C. To address the question\, unstable neutron-rich nuclei provide a great 
 opportunity. Unstable neutron-rich nuclei typically have large neutron exc
 ess\, which enables to study the proton-neutron-asymmetry dependence in a 
 wide range. Furthermore\, the question how SRC pair behaves in extreme neu
 tron-rich environment arises and such a question may provide key informati
 on on the equation of state for neutron stars.\n\nAiming at studying the S
 RC in neutron-rich short-lived nuclei\, we propose a novel method\, namely
  proton-induced deuteron-knockout reaction with fast beams of unstable neu
 tron-rich nuclei in inverse kinematics\, to measure the momentum distribut
 ion inside SRC pairs. The experiment will be conducted using the SAMURAI s
 pectrometer at the RI beam factory\, RIKEN. In this presentation\, the new
  method will be discussed\, and experimental details will be given.\n\nhtt
