TL;DR
This study investigates the Gamow-Teller transition from 14Be to 14B using an inverse kinematics (p,n) reaction at 69 MeV/nucleon, revealing excitation states and transition strengths consistent with previous beta decay data.
Contribution
First measurement of the 14Be(p,n)14B reaction at this energy, providing detailed spectroscopic information and validating theoretical models of GT transitions in drip-line nuclei.
Findings
Observed a peak at 1.27 MeV in 14B with GT character.
Measured differential cross sections consistent with DWBA calculations.
Deduced GT transition strength matching beta decay results.
Abstract
A Gamow-Teller (GT) transition from the drip-line nucleus 14Be to 14B was studied via the (p,n) reaction in inverse kinematics using a secondary 14Be beam at 69 MeV/nucleon. The invariant mass method is employed to reconstruct the energy spectrum. A peak is observed at an excitation energy of 1.27(2) MeV in 14B, together with bumps at 2.08 and 4.06(5) MeV. The observed forward peaking of the state at 1.27 MeV and a good description for the differential cross section, obtained with a DWBA calculation provide support for the 1+ assignment to this state. By extrapolating the cross section to zero momentum transfer the GT-transition strength is deduced. The value is found to compare well with that reported in a beta-delayed neutron emission study.
