The astrophysical S factor for 11C(p,7)12N. The nonresonance capture component is shown as a dashed line and the total S factor is given by the solid line. We recently completed a measurement of the 14N(3He,d)150 reaction. The experiment was carried out with a 3He beam obtained from the U120 cyclotron at Rez. The ANCs for 15O - 14N + p will fix the non-resonant capture rate for 14N(p,7)150. A recent measurement of the lifetime of the excited state in 150 at Ex 6.79 MeV indicates19...

Institut de Physique Nucl aire, Universit Paris-Sud, F-91406 Orsay Cedex, One of the standard tools for nuclear structure calculations is the random phase approximation (RPA) with the self-consistent mean-field derived with making use of the Skyrme-type interactions1. Such models are quite successful for predicting properties of collective states 2-3> 4-5. It is well known that due to the anharmonicity of vibrations there is a coupling between one-phonon and more complex states 6'7. The main...

Analysis Of Various Detector Signals Digitized By A 12bit Flash

RUDOLF Institut de Recherches Subatomiques, IN2P3 23, Rue du Loess, BP 28 67037, Strasbourg, FRANCE E-mail strahinja.lukic ires.in2p3.fr A flash ADC with 100 MHz sampling frequency and 12 bit resolution is used to digitize the signals of several types of detectors. Mathematical algorithms are performed on the digitized signals to obtain energy, timing, and pulse shape information. The detectors involved in the study are HPGe (in-beam prompt gamma spectroscopy for (n,xn)...

Where e denotes the number of oscillator quanta in some completely filled SU3 shell, but e0 - the number of oscillator quanta in the last unfilled SU3 shell. The classification of SU3 states in nuclei is based on plethysm operation eo , employing the oscillator energy of the last unfilled SU3 shell, and as a result one obtains for each Young pattern the possible IRs Ei,E2,E3 of group SU3 as well as their multiplicity indexes a. 2. Calculations of nuclear SU3 state classification The reduction...

Fifty Years Of Neutron Capture

CHRIEN Brookhaven National Laboratory A half century of neutron capture is reviewed. The development of this field and its personal impact on one research scientist are discussed. Fifty years have passed since capture reaction studies, and especially the neutron capture techniques with high resolution, began to impact the study of nuclei. While the study of nuclei through radioactivity became important near the end of the nineteenth century, it was not until after World War II, with...
