Abstract

Calculations on the ground state of HT and CH{sub 3}T and the excited states of HHe{sup +} and CH{sub 3}He{sup +} have been carried out within the sudden approximation to test alternative approaches to existing problems, with the ultimate aim of studying the effects of a molecular environment on the detailed energetics of tritium {beta} decay. By using an appropriate projection operator most of the transition probability has been accounted for. Commonly used sum rules are shown to have limited utility. The inaccuracies introduced by describing an excited state by a single spin-adapted configuration are discussed. The problem of determining transition probabilities from configuration-interaction wave functions is highlighted and some solutions are proposed.

Final-state spectrum of {sup 3}He after {beta}{sup -} decay of tritium anions T{sup -}

Journal Article Stark, Alexander; Saenz, Alejandro - Physical Review. A

The final-state spectrum of {beta} decaying tritium anions T{sup -} was calculated. The wave functions describing the initial T{sup -} ground state and the final {sup 3}He states were obtained by the full configuration-interaction method. The transition probability was calculated within the sudden approximation. The transition probability into the electronic continuum was extracted from the complex-scaled resolvent and shown to converge for very high energies to an approximate analytical model probability distribution.

Molecular effects in tritium. beta. decay. II. Rotation-vibration excitation, dissociation, and rotational predissociation in the decay of the T/sub 2/ and TH molecules

Journal Article Jeziorski, B; Kolos, W; Szalewicz, K; ... - Phys. Rev. A; (United States)

Probabilities have been computed for transitions induced by a ..beta..-decay process from the ground rovibronic state of the T/sub 2/ molecule to various bound rovibrational and scattering states connected with the first six /sup 1/..sigma../sup +/ electronic states of the /sup 3/HeT/sup +/ ion. Analogous calculations were performed for the TH source but only the ground electronic state of the daughter system was considered. For transitions from the T/sub 2/ source to the ground electronic state of the daughter ion a probability equal to 0.4083 is associated with bound rovibrational states while 0.1659 is associated with scattering states.

Molecular effects in the neutrino mass determination from beta-decay of the tritium molecule

Conference Fackler, O; Jeziorski, B; Kolos, W; ...

Molecular final state energies and transition probabilities have been computed for beta-decay of the tritium molecule. The results are of sufficient accuracy to make a determination of the electron neutrino rest mass with an error not exceeding a few tenths of an electron volt. Effects of approximate models of tritium beta-decay on the neutrino mass determination are discussed. 14 refs., 3 figs., 1 tab.

Molecular effects in investigations of tritium molecule {beta} decay endpoint experiments

Journal Article Doss, Natasha; Tennyson, Jonathan; Saenz, Alejandro; ... - Physical Review. C, Nuclear Physics

The final state distribution of the first six electronic states of {sup 3}HeT{sup +},{sup 3}HeD{sup +} and {sup 3}HeH{sup +} resulting from the {beta} decay of T{sub 2}, DT, and HT are calculated, to satisfy the higher-resolution requirements and increased sensitivity of the future tritium neutrino mass experiments. The sensitivity of the initial temperature, ortho-para ratio, and isotopic composition of the source is considered. Estimates of the error in the value of the neutrino mass deduced from fitting, due to uncertainties in the temperature, the ortho-para ratio of T{sub 2}, and the percentage of DT molecules in the source aremore » presented.« less
