In this work we discuss the results of a recent HELIOS [1] measurement of the (d,p) reaction on 18F, from both the ground (1+ ) and isomeric (5+) states, to the members of the 19F ground-state band [2] in the rotational model
We consider the structure of 18,19F in terms of Nilsson single-particle orbits originating from the sd spherical levels coupled to a deformed core, and calculate the...
In recent years, significant progress has been made in ab initio nuclear structure and reaction calculations based on input from QCD employing Hamiltonians constructed within chiral effective field theory. One of the modern approaches is the No-Core Shell Model with Continuum (NCSMC) [1,2], capable of describing both bound and scattering states in light nuclei simultaneously. We will present...
Accurate studies on 13C spectroscopy have great impact in the present understanding of the role played by extra-neutrons in stabilizing alpha-cluster structures formed in light nuclei. 13C excited states are in fact the simplest systems that can be formed by adding a neutron to a triple-alpha molecular-like structure. Their spectroscopic properties are therefore a fundamental benchmark for...
The interaction of neutrons with 7Be that was measured at the SARAF in Israel with a quasi-Maxwellian neutron beam at 49.5 keV reveals a strong B(E1: 2- ---> 2+) ~ 0.04 W.u., decay of the 2- state at 18.91 MeV in 8Be to the alpha-cluster 2+ state at 3.03 MeV [1]. This strong E1 decay leads to large cross section of the 7Be(n,g_1)*8Be(3.03) reaction at the “BBN window". It implies s-waves...
