Abstract

Excitation functions have been measured for a number of (⁴⁰Ar, xn), (⁴⁰Ar, pxn), (⁴⁰Ar, 2pxn), and (⁴⁰Ar, 3pxn) reactions induced in ¹¹⁸Sn, ¹²¹Sb and ¹²⁷I over the lab. energy interval 150–280 MeV. Values of the total fusion cross section are obtained and J_crit is deduced. The value of J_crit increases with energy and becomes as large as 110–140ħ, in reasonable agreement with the yrast limit deduced from the ellipsoidal liquid drop model. The competition between proton and neutron emission from the compound nucleus is examined and $Γ_{p} Γ_{n}$ is found to increase rapidly with the number of emitted nucleons, thereby imposing severe limits on the production of very neutron deficient miclides via compound nuclear reactions. The effect of very high angular momentum on the excitation functions is examined.

1976, Nuclear Instruments and Methods
The He-jet transport systems for use with the heavy-ion accelerator ALICE at Orsay are described in detail. The dependence of the gas flow rate on various parameters (pressure, length and diameter of the capillary) was investigated. Off-line measurements were carried out with a ²⁵²Cf source. Effect on collection yield of UV radiation and additives to the helium was checked. The influence of the distance between the target and the capillary on the collection efficiency for short-lived isotopes of Yb was investigated. Some other useful are details are also discussed (collector, volume of the reaction chamber, etc.). Various applications of the He-jet method are described: particle identification, angular distribution of reaction products, mass identification of radioactive nuclei.
Fission of medium and heavy nuclei induced by <sup>40</sup>Ar from 160 to 300 MeV: Cross sections
1975, Nuclear Physics, Section A
Cross sections have been measured for argon-induced fission following full momentum transfer. Two incident energies (between 200 and 300 MeV) have been used for ²³⁸U, ²⁰⁹Bi, ¹⁶⁵Ho and ^natMo targets. For a ^natSb target, the fission excitation function has been measured from 160 to 300 MeV. The experimental method was an improved version of the angular correlation method, which takes into account kinetic energies and time-of-flight correlations. This allowed us to eliminate fission events following transfer reactions and also random events. Assuming that the angular distribution is that characteristic of fission fragments issued from a compound nucleus (close to 1/sinθ) the fission cross sections range from 10 ± 1 mb for Ar + Mo at 200 MeV to 1030 ± 120 mb for Ar + U at 300 MeV. When necessary, these cross sections have been added to the cross sections for the formation of evaporation-residue nuclei measured by other authors in order to obtain complete-fusion cross sections. The deduced critical angular momentum for formation of a complete-fusion nucleus are found to be an increasing function of the mass and energy of the incoming particle. These results are used to test the concept of a critical distance of approach which would govern fusion between two complex nuclei. The threshold of the excitation function measured for Ar + Sb is compared with calculations based on the statistical model for the competition between fission and evaporation. These calculations include the effects of multiple-chance fission and of angular momentum on fission widths.

Chemical effects in the collection of mercury isotopes with the He-Jet transport method
1975, Nuclear Instruments and Methods
The helium-jet system in use at Orsay is briefly described. An experiment has been performed which demonstrates the importance of the choice of the impurities added to the He gas carrier. Mercury isotopes produced in the reactions $^{144} Nd (^{40} Ca, x n)$ ^184−xHg are not collected by the helium-jet method under normal conditions. It is shown that the addition of iodine (which easily reacts with mercury) to the helium gas is a very efficient way to collect the mercury isotopes.
