The new neutron-deficient nuclei 240Es and 236Bk were synthesised at the gas-filled recoil separator RITU. They were identified by their radioactive decay chains starting from 240Es produced in the fusion–evaporation reaction 209Bi(34S,3n)240Es. Half-lives of 6(2) sand 22+13−6swere obtained for 240Es and 236Bk, respectively. Two groups of αparticles with energies Eα=8.19(3) MeVand 8.09(3) MeVwere unambiguously assigned to 240Es. Electron-capture delayed fission branches with probabilities of 0.16(6)and 0.04(2)were measured for 240Es and 236Bk, respectively. These new data show a continuation of the exponential increase of ECDF probabilities in more neutron-deficient isotopes.

Search for Electron-Capture Delayed Fission in the New Isotope 244Md

Khuyagbaatar, J.; Albers, H. M.; Block, M.; Brand, H.; Cantemir, R. A.; Di Nitto, A.; Düllmann, Ch. E.; Götz, M.; Götz, S.; Heßberger, F. P.; Jäger, E.; Kindler, B.; Kratz, J. V.; Krier, J.; Kurz, N.; Lommel, B.; Lens, L.; Mistry, A.; Schausten, B.; Uusitalo, J.; Yakushev, A. (American Physical Society (APS), 2020)

The electron-capture decay followed by a prompt fission process was searched for in the hitherto unknown most neutron-deficient Md isotope with mass number 244. Alpha decay with α-particle energies of 8.73–8.86 MeV and ...

R.; Recchia, F.; Siciliano, M.; Testov, D.; Szilner, S.; Zanon, I. (Elsevier, 2023)

This work aims at presenting an alternative approach to the long standing problem of the B(E2) values in Sn isotopes in the vicinity of the N=Z double-magic nucleus 100Sn, until now predominantly measured with relativistic ...
High-precision electron-capture Q value measurement of 111In for electron-neutrino mass determination

Ge, Z.; Eronen, T.; de Roubin, A.; Tyrin, K.S.; Canete, L.; Geldhof, S.; Jokinen, A.; Kankainen, A.; Kostensalo, J.; Kotila, J.; Krivoruchenko, M.I.; Moore, I.D.; Nesterenko, D.A.; Suhonen, J.; Vilén, M. (Elsevier, 2022)

A precise determination of the ground state 111In (9/2+) electron capture to ground state of 111Cd (1/2+) Q value has been performed utilizing the double Penning trap mass spectrometer, JYFLTRAP. A value of 857.63(17) keV ...

The ground state to ground state electron-capture Q value of 159Dy (3/2−) has been measured directly using the double Penning trap mass spectrometer JYFLTRAP. A value of 364.73(19) keV was obtained from a measurement of ...
Electron-capture decays mimicking axionic transitions

Agnihotri, Aagrah (2024)

For the first time, estimates for β decay rates are made that are necessary for experimental searches of low-mass axions. Low-mass axions are potential dark matter candidates, hence, searches of low-mass axions have ...
