چکیده
The structure of the unbound F15 nucleus is investigated using inverse kinematics resonant scattering a radioactive O14 beam impinging on CH2 target. analysis H1(O14,p)O14 and H1(O14,2p)N13 reactions allowed confirmation previously observed narrow 1/2? resonance, near two-proton decay threshold, identification two new 5/2? 3/2? resonances. newly levels by 1p emission to ground O14, sequential 2p state N13 via 1? resonance O14. Gamow shell model (GSM) experimental data suggests that wave functions resonances may be collectivized continuum coupling nearby 2p- 1p-decay channels. excitation function spectrum in are well reproduced unified framework GSM.Received 1 December 2021Accepted 7 April 2022DOI:https://doi.org/10.1103/PhysRevC.105.L051301©2022 American Physical SocietyPhysics Subject Headings (PhySH)Research AreasNuclear reactionsNuclear & decaysResonance reactionsProperties6 ?

First observation of the unbound nucleus 15Ne.
We report on the first observation of the unbound proton-rich nucleus 15Ne. Its ground state and first excited state were populated in two-neutron knockout reactions from a beam of 500 MeV/u 17Ne. The 15Ne ground state is found to be unbound by 2.522(66) MeV. The decay proceeds directly to 13O with simultaneous two-proton emission. No evidence for sequential decay via the energetically allowed ...
متن کاملIntense, narrow atomic-clock resonances.
We present experimental and theoretical results showing that magnetic resonance transitions from the "end" sublevels of maximum or minimum spin in alkali-metal vapors are a promising alternative to the conventional 0-0 transition for small-size gas-cell atomic clocks. For these "end resonances," collisional spin-exchange broadening, which often dominates the linewidth of the 0-0 resonance, decr...
متن کاملRemarks on the Parity Determination of Narrow Resonances ∗
Recently several proposals were put forward to determine the parity of narrow baryonic resonances, in particular the Θ +. In these proceedings we will briefly comment on the general problems in this task and then discuss in detail the potential of reactions of the type N N → Θ + Y , where Y denotes a hyperon (either Σ or Λ) and the arrows indicate that a polarized initial state is required. Bes...
متن کاملVery Narrow Resonances in Spherical Proton Emitting Nuclei
The separation energy and half-life of some heavy proton emitting nuclei, and the single-particle structure of the unbound 11N , have been evaluated by implementing a careful numerical treatment to solve Schrödinger equation in a continuum discretization context. The basic scheme behind the method consists in using the ground-state proton emitter in connection with an isolated single-particle r...
