The Program Advisory Committees (PAC) are incharge of reviewing the scientiﬁc proposals submitted
for the use of the accelerator facility in the RIKEN
Nishina Center (RNC). Two PAC meetings were heldin ﬁscal year 2021; one for proposals in the ﬁeld of
nuclear physics (NP-PAC), and one for proposals in
the ﬁeld of materials and life sciences (ML-PAC).
NP-PACThe 22nd NP-PAC meeting was held from December 1 to December 3, 2021,1) with the attendance of 16
PAC members. As oversea travels were diﬃcult due to

M. Dasgupta (The Australian National University),
J. Dilling (Oak Ridge National Laboratory), M. Gorska(GSI), T. Kawabata (Osaka University), M. Matsuo(Niigata University), R. Zegers (Michigan State University). M. J. G. Borge from CSIC, Madrid, had
newly taken on the role of chairperson of the meeting.
31 proposals were reviewed, and 1 proposal and 13 proposals were approved as grade S and A, respectively.
