Title: Dipole response of the odd-proton nucleus ²⁰⁵Tl up to the neutron-separation energy

Abstract

The low-lying electromagnetic dipole strength of the odd-proton nuclide ²⁰⁵Tl has been investigated up to the neutron separation energy exploiting the method of nuclear resonance fluorescence. In total, 61 levels of ²⁰⁵Tl have been identified. Lastly, the measured strength distribution of ²⁰⁵Tl were discussed and compared to those of even–even and even–odd mass nuclei in the same mass region as well as to calculations that have been performed within the quasi-particle phonon model.

Fragmentation of low-lying dipole strength in the odd-mass nucleus {sup 133}Cs

Journal Article Besserer, J ; Beck, O ; Eckert, T ; ... - Physical Review, C

The fragmentation of low-lying dipole strength in the odd-mass nucleus {sup 133}Cs has been investigated in nuclear resonance fluorescence (NRF) experiments performed at the bremsstrahlung beam of the Stuttgart Dynamitron accelerator at an end-point energy of 4.1 MeV. In the excitation energy range 2.3 {endash} 3.7 MeV in total 22 new dipole excitations were observed. From the high-resolution {gamma}-ray spectra measured by three high-efficiency Ge detectors the reduced excitation probabilities B(E1){up_arrow} or B(M1){up_arrow} were deduced. The fragmentation and absolute total strengths of the detected dipole excitations are compared with results for the neighboring even-even, {gamma}-soft nucleus {sup 134}Ba, where both,more »« less

Strength function for $gamma$ lines of $sup 205$Tl at excitation energies up to 7.5 MeV (in Russian)

Journal Article Earle, E D ; Knowles, J W ; Lone, M A ; ... - Izv. Akad. Nauk SSSR, Ser. Fiz., v. 37, no. 9, pp. 1904-1910

The cross section for the quasi-elastic scattering /sup 205/Tl( gamma , gamma )/sup 2 05/Tl of photons with energies from 3.5 to 7.5 MeV was measured. The intensity of the scattered photons was measured, and the dependence of the quasi-elastic scattering cross section on the energy of the incident photons was determined. It is shown that the irregularitics in the behavior of the strength function of the /sup 205/Tl gamma rays are a feature of the strength function for three Tl isotopes both during excitation with photons and in neutron capture reactions.

First identification of dipole excitations to a 2[sup +][direct product]3[sup [minus]][direct product]particle multiplet in an odd-[ital A] nucleus

Journal Article Zilges, A ; Herzberg, R ; von Brentano, P ; ... - Physical Review Letters; (United States)

A photon scattering experiment has been performed on the odd-[ital A] nucleus [sup 143]Nd. Strong dipole excitations have been detected in the energy region around 3.2 MeV. This is near the expected position of the two-phonon (2[sup +][direct product]3[sup [minus]]) multiplet in the even-even neighboring nucleus [sup 142]Nd. The summed dipole strength between 2.8 and 3.6 MeV in [sup 143]Nd is in agreement with the sum rule for weak particle coupling to the core nucleus [sup 142]Nd. Model calculations in a harmonic approximation are in a very good agreement with the experiment and they suggest a two-phonon (2[sup +][direct product]3[supmore »« less

CeNTREX: a new search for time-reversal symmetry violation in the ²⁰⁵Tl nucleus

Journal Article Grasdijk, Olivier ; Timgren, O. ; Kastelic, J. ; ... - Quantum Science and Technology

The Cold molecule Nuclear Time-Reversal EXperiment (CeNTREX) is a new effort aiming for a significant increase in sensitivity over the best present upper bounds on the strength of hadronic time reversal (T) violating fundamental interactions. The experimental signature will be shifts in nuclear magnetic resonance frequencies of ²⁰⁵Tl in electrically-polarized thallium fluoride (TlF) molecules. Here we describe the motivation for studying these T-violating interactions and for using TlF to do so. To achieve higher sensitivity than earlier searches for T-violation in TlF, CeNTREX uses a cryogenic molecular beam source, optical state preparation and detection, and modern methods of coherent quantummore »« less

Dipole strength distributions in the stable Ba isotopes {sup 134-138}Ba: A study in the mass region of a nuclear shape transition

Journal Article Scheck, M ; Garrel, H von ; Belic, D ; ... - Physical Review. C, Nuclear Physics

The low-lying dipole strength distributions in the odd-mass isotopes {sup 135,137}Ba were studied in nuclear resonance fluorescence experiments (NRF) performed at the Stuttgart Dynamitron facility using bremsstrahlung beams with end point energies of 4.1, 3.1, and 2.5 MeV. Numerous excited states, most of them unknown so far, were observed in the excitation energy range up to 4 MeV. Detailed spectroscopic information has been obtained on excitation energies, decay widths, decay branching ratios, and transition probabilities. The results for {sup 137}Ba are compared with calculations in the framework of the Quasiparticle-Phonon Model. The new data for {sup 135,137}Ba complete the systematicsmore »« less
