H4nucleus and theH

Abstract

The H(t, tp)n reaction was investigated in a kinematically complete experiment with a tritium beam at energies around 35 MeV. Evidence was found for the H ground state. Coincidence spectra were fitted by the contribution of quasifree processes, sequential decay through the He ground state, and the n-p final-state interaction. The best agreement with the data was obtained assuming the following H ground-state parameters: E"=3.1 MeV and y =2.3 MeV.

“…11(a) 5 MeV, respectively. The theoretical prediction of the spectator-neutron momentum distribution has been obtained using the square of the wave function in momentum space [47]. As we can see the agreement with the PWIA is not satisfactory.…”

Theory of the Trojan-Horse Method − From the Original Idea to Actual Applications

“…They studied momentum distributions of clustered nuclei extensively [8,9] and performed tests of the cross section factorization in PWIA [10]. Furthermore, many experiments investigating quasifree scattering and reactions were conducted [11][12][13][14][15][16][17]. Hence it is not a surprise that Claudio Spitaleri became interested in the TH method.…”

Resonances of $A=4$ $T=1$ isospin triplet states within the \textit{ab initio} no-core Gamow shell model

“…Four-nucleon (4N ) systems are the lightest nuclear systems to exhibit resonances at low energies [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. With the highest isospin quantum number of |T z | = T = 2, the possible tetraneutron resonance has attracted considerable attention due to its pure neutron character.…”

“…By reducing the isospin quantum number, 4 H, 4 He and 4 Li form a unique T = 1 isospin triplet of 4N resonances with many experimental data available . However, the data providing the energies and widths of the A = 4 resonances are neither conclusive nor even consistent with each other [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. In the experiments where the missing mass method is used, the resonance positions in energy distributions depend on the resonance parameters [22].…”
