Exploring the mass radius of ⁴He and implications for nuclear structure

NUCLEAR REACTIONS ⁴He(γ, φ), E=1.785-2.335 GeV; analyzed experimental results from LEPS Collaboration on coherent φ-meson photoproduction of ⁴He nucleus; deduced mass radii. No noticeable discrepancy between the charge radius and the mass radius is noted for the ⁴He nucleus.
