Abstract
Abstract
The complete fusion reaction of
Mn +
Tb was studied on the gas-filled recoil separator SHANS2. Nineteen ER - α
- α
decay chains from
Th produced from the 4n evaporation channel were observed. The α-particle energy and half-life of
Th were determined as 7922(14) keV and 14(4) ms, respectively. In addition, the decay properties of
= 7788(14) keV and
= 36
ms were obtained for
Th. The measured α decay properties of
Th and
Th were consistent with literature data. The cross sections were measured to be 0.59
nb and 0.19
nb for
Th and
Th, respectively. The equilibrium charge state of the recoiled nucleus
Th was determined experimentally. The new data were helpful for estimating the equilibrium charge states of elements 119 and 120, which could be produced via the
Pu(
Mn, 3n)
119 and
Am(
Mn, 3n)
120 reactions, respectively.
