“…Using the temperature as a variable parameter allowed us to generate different shapes of f E1 function. The concept of the constant temperature is also consistent with the experimental level density for 56 Fe [14] which is better reproduced by the constant temperature model. In order to describe the low-energy enhancement of the γ-strength function analytically, the exponential parametrization was adopted.…”

Abstract. The multipolarity of the low-energy (< 3 MeV) γ−strength function has been experimentally studied with the 55 Mn(p,2γ) 56 Fe reaction at 1.65 MeV proton beam energy. The spectrum of two-step γ−cascades populating the ground state of 56 Fe has been measured and compared with calculations assuming that E1 or M1 multipolarities dominate in the low-energy region. It was found that experimental data points are reproduced only if the assumption on dominance of the M1 multipolarity is used.

“…Another experimental method to obtain the nuclear level density in the energy range between the ground state and the neutron separation energy is the measurements of particle evaporation spectra from compound nuclear reactions [3]. The level density is extracted from the spectra of outgoing particles.…”

“…In this work, the level density of 90 Zr was studied from the (d, n) reaction on 89 Y. The motivation of the choice of the 90 Zr nucleus is to study the level density of heavier nuclei compared to those we studied in our early works [3]. In addition, 90 Zr is a closed-shell nucleus with 40 protons and 50 neutrons.…”

Experimental elastic scattering and double differential cross sections of 89 Y(d, n) and 89 Y(d, p) reactions have been measured with 5, 6 and 7.44 MeV deuteron beams. It was found that about 76% of the total reaction cross section is determined by compound mechanism and rest is due to direct and pre-equilibrium interactions. Cross sections measured at backward angles were compared with calculations based on the compound nuclear Hauser-Feshbach model. It was found that it is possible to reproduce the backward angle neutron cross sections by compound model but it fails to describe proton cross sections. A pronounced peak is observed in neutron differential cross section which might result from strongly populated states 0 + , 4 − , and 5 − of 90 Zr via direct stripping reactions. The level density of 90 Zr has been obtained from neutron cross sections measured at backward angles. It is best described with the constant temperature level density model versus the traditional Fermi-gas one.

“…However, there are already notable contributions to deuteron-induced reaction studies (e.g., Refs. [2][3][4][5][6]) that have taken into account only the statistical emission and eventually a "reduction factor" of the compound nucleus cross section due to "direct processes." Moreover, this reduction factor does not allow the distinction between processes such as the breakup and the stripping mechanisms that affect the different energy ranges of particles emitted through the decay of excited composite nuclei.…”

Experimental elastic-scattering angular distributions for deuteron interaction with 63 Cu and 93 Nb targets are compared with calculations performed within the continuum-discretized coupled-channels (CDCC) method, in which coupling to breakup channels is explicitly taken into account. The calculated elastic breakup cross sections are compared with the predictions of an empirical parametrization for a wide range of deuteron incident energies. The good agreement between the calculations and the systematics at the energies where data are available indicates that the CDCC method permits a useful assessment of empirical parametrizations and provides useful guidance for the extrapolation of these parametrizations beyond the energies formerly considered.
