High spin band structures in doubly-odd $^{194}$Tl
Abstract
The high-spin states in odd-odd Tl nucleus have been studied by populating them using the Re(C, xn) reactions at 75 MeV of beam energy. coincidence measurement has been performed using the INGA array with a digital data acquisition system to record the time stamped data. Definite spin-parity assignment of the levels was made from the DCO ratio and the IPDCO ratio measurements. The level scheme of Tl has been extended up to 4.1 MeV in excitation energy including 19 new gamma ray transitions. The band, in the neighboring odd-odd Tl isotopes show very similar properties in both experimental observables and calculated shapes. Two new band structures, with 6-quasiparticle configuration, have been observed for the first time in Tl. One of these bands has the characteristics of a magnetic rotational band. The cranked shell model calculations, using a deformed Woods-Saxon potential, have been performed to obtain the total Routhian surfaces in order to study the shapes of the bands and the band crossing in Tl. The semiclassical formalism has been used to describe the magnetic rotational band.
