Forty-six decay chains, assigned to the decay of ²⁸⁸115, were produced using the ²⁴³Am(⁴⁸Ca,3n) ²⁸⁸115 reaction at the Lawrence Berkeley National Laboratory 88-in. cyclotron. The resulting series of α decays were studied using α-photon and α-x-ray spectroscopies. Multiple α-photon coincidences were observed in the element 115 decay chain members, particularly...

In Section 1 we will discuss multi-nucleon transfer reactions with light heavy ions, which can be thought of as competing with complete fusion at higher impact parameters. Quasi-elastic and multi-nucleon transfer reactions with the heaviest projectiles will be discussed in Section 2. In Section 3 we will cover recent developments...

The yields of over 200 projectile-like fragments (PLFs) and target-like fragments (TLFs) from the interaction of (E[subscript]c.m.=450 MeV) Xe¹³⁶ with a thick target of Pb²⁰⁸ were measured using Gammasphere and off-line γ-ray spectroscopy, giving a comprehensive picture of the production cross sections in this reaction. The measured yields were compared...
Background: Multinucleon transfer reactions have recently attracted attention as a possible path to the synthesis of new neutron-rich heavy nuclei.
Purpose: We study transfer reactions involving massive nuclei with the intention of understanding if the semi-classical model GRAZING coupled to an evaporation and fission competition model can satisfactorily reproduce experimental...
The fission Time Projection Chamber (fissionTPC) is a compact (15 cm diameter) two-chamber
MICROMEGAS TPC designed to make precision cross-section measurements of neutron-induced fission.
The actinide targets are placed on the central cathode and irradiated with a neutron beam that passes
axially through the TPC inducing fission in the target....
We have studied the fission-neutron emission competition in highly excited ²⁷⁴Hs (Z = 108) (where the
fission barrier is due to shell effects) formed by a hot fusion reaction. Matching cross bombardments
(²⁶Mg + ²⁴⁸Cm and ²⁵Mg + ²⁴⁸Cm) were used to identify the properties of first chance fission of...
Abstract: Background: The cross section for forming a heavy evaporation residue in fusion reactions depends on the capture cross section, the fusion probability, P[subscript CN], i.e., the probability that the projectile-target system will evolve inside the fission saddle point to form a completely fused system rather than reseparating (quasifission), and...
Background: There is a long-term interest in running the fission reaction backward, i.e., studying the "inverse fission" of uranium. The recent availability of beams of n-rich fission fragments has stimulated interest in this endeavor.
Purpose: To search for inverse fission in the reactions Sn-¹²⁴,Sn-¹3² + Mo-¹⁰⁰.
Method: In the Sn-¹²⁴...
