/ Tiberio, A (INFN, Florence) ; Adriani, O (INFN, Florence ; Florence U.) ; Berti, E (INFN, Florence ; Florence U.) ; Betti, P (INFN, Florence ; Florence U.) ; Bonechi, L (INFN, Florence) ; Bongi, M (INFN, Florence ; Florence U.) ; D'Alessandro, R (INFN, Florence ; Florence U.) ; Detti, S (INFN, Florence) ; Haguenauer, M (Ecole Polytechnique) ; Itow, Y (Nagoya U., ISEE ; KMI, Nagoya) et al.
The LHC-forward experiment (LHCf), located at the Large Hadron Collider (LHC), is designed to
measure the production cross section of neutral particles in the very-forward region, covering the
pseudorapidity region above 8.4 (up to zero-degree particles). By measuring the very-forward
particle production rates at the highest energy possible at an accelerator, LHCf will provide
fundamental informations to improve phenomenological hadronic interaction models used in the
simulation of air-showers induced by ultra-high-energy cosmic rays in the atmosphere. [...]

Intruder configurations in $^{29}$Ne at the transition into the island of inversion: Detailed structure study of $^{28}$Ne
/ Wang, H. (RIKEN (main)) ; Yasuda, M. (Tokyo Inst. Tech.) ; Kondo, Y. (Tokyo Inst. Tech.) ; Nakamura, T. (Tokyo Inst. Tech.) ; Tostevin, J.A. (Tokyo Inst. Tech. ; Surrey U.) ; Ogata, K.

(JAEA, Ibaraki) et al.
Detailed $\gamma$-ray spectroscopy of the exotic neon isotope $^{28}$Ne has been performed for the first time using the one-neutron removal reaction from $^{29}$Ne on a liquid hydrogen target at 240~MeV/nucleon. Based on an analysis of parallel momentum distributions, a level scheme with spin-parity assignments has been constructed for $^{28}$Ne and the negative-parity states are identified for the first time.

Status and Prospects of the LHCf and RHICf experiments
/ LHCf Collaboration
Precise understanding of hadronic interactions at high energies is a key to improve mass composition measurements of very high energy cosmic-rays and to solve the muon excess issue observed in high energy cosmic-ray experiments using an air-shower technique. The LHCf and RHICf experiments measures the differential production cross sections of very forward neutral particle as photons, neutral pions and neutrons at LHC and RHIC, respectively. [...]

The LHCf forward (LHCf) experiment measures the production cross sections of neutral particles emitted to the very forward region of an LHC interaction point in order to test the hadronic interaction models used in air-shower simulations. In this proceedings, we present the neutron and $\pi^0$ spectra measured in $pp$ collisions at $\sqrt{s}$ = 13 TeV. [...]
