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 ...
Analysis of the charge state distribution produced in a 78Kr + 98Mo fusion evaporation reaction utilizing the MARA separator

Lightfoot, Alexandra (2016)

Experimental results on the charge state distribution of the fusion evaporation reaction 78Kr + 98Mo are presented. The data has been taken from the 1st commissioning run of MARA (Mass Analysing Recoil Apparatus). Data ...

(Elsevier, 2024)

This letter reports on the first observation of an octupole band in the neutron-deficient (N = Z + 2) nucleus 110Xe. The 110Xe nuclei were produced via the 54Fe(58Ni,2n) fusion-evaporation reaction. The emitted γ rays were ...
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 ...
