This phenomenon has significant relevance considering the remarkable achievements of the shell model and the SDPF-U interaction in the region which is able to predict the fading of the N = 28 shell gap in neutron-rich 44S. Recent measurements narrowed down this discrepancy to an overestimation of the proton amplitude to the quadrupole transition matrix element. The current work aims to propose a different perspective on the puzzle, by studying a direct proton-transfer reaction on 46Ar as a means to directly probe the proton wavefunction of the ground state this isotope. By measuring the amount of l = 0 transfer to the ground state (1/2+) of 47K with respect to the l = 2 to the first excited state (3/2+), we aim to gain insight into the ground state proton wavefunction of 46Ar. We will present a brief description of the experiment performed at the SPIRAL1 facility in GANIL (France). The experimental apparatus allowed a full reconstruction of the two-body reaction thanks to the combination of AGATA, VAMOS, MUGAST, CATS2, and HECTOR PB IOP Publishing SN 1742-6588 SN 1742-6596 (electrónico) YR 2023 FD 2023 LK https://hdl.handle.net/10272/22704 UL https://hdl.handle.net/10272/22704 LA eng NO Brugnara, D., Gottardo, A., Assié, M., Mengoni, D., Lemasson, A., Clement, E., Flavigny, F., Ramos, D., Galtarossa, F., Matta, A., Girard-Alcindor, V., Babo, M., Bazzacco, D., Beaumel, D., Blumenfeld, Y., Bottoni, S., Datta, U., de Angelis, G., de France, G., … Zielinska, M.
